+# Bulk Insert Attachments
+
+---
+
+{NOTE: }
+
+* [bulk_insert](../../client-api/bulk-insert/how-to-work-with-bulk-insert-operation) is RavenDB's 
+  high-performance data insertion operation.  
+  Use its `attachments_for` interface to add attachments to multiple documents with great speed.  
+* Use `store` 
+
+* In this page:  
+    * [Usage flow](../../document-extensions/attachments/bulk-insert#usage-flow)  
+    * [Usage example](../../document-extensions/attachments/bulk-insert#usage-example)
+
+{NOTE/}
+
+{PANEL: Usage flow}
+
+* Create a `bulk_insert` instance.  
+
+* Pass the Document ID to the instance's `attachments_for` method.
+
+* To add an attachment, call the `store` method.  
+  Pass it the attachment's name, stream, and type (optional).  
+  `store` can be called repeatedly, as many times as needed.  
+
+* Note:  
+  If an attachment with the specified name already exists on the document,  
+  the bulk insert operation will overwrite it.
+
+{PANEL/}
+
+{PANEL: Usage example}
+
+In this example, we attach a file to all User documents that match a query.

+# Attachments: Copy, Move, Rename
+
+Attachments can be copied, moved, or renamed using built-in session methods.  
+All of those actions are executed when `save_changes` is called and take place on the server-side,  
+removing the need to transfer the entire attachment binary data over the network in order to perform the action.

+{NOTE/}
+
+---
+
+{PANEL: }
+
+### Counters and Indexing  
+
+Indexing Counters can speed-up finding them and the documents that contain them.  
+
+* **Indexing Counter Values**
+    Dynamic indexes (aka auto-indexes) _cannot_ index counter values. To index counter values, 
+    create a static index that inherits from `AbstractCountersIndexCreationTask` ([see here](../../document-extensions/counters/indexing)).
+
+* **Indexing Counter Names**  
+    Re-indexing due to Counter-name modification is normally rare enough to pause no performance issues.  
+    To index a document's Counters by name, use [CounterNamesFor](../../document-extensions/counters/indexing#section-1).  
+
+---
+
+###Counters and Queries  
+
+Create queries **using code**, or send the server **raw queries** for execution.  
+
+* Either way, you can query Counters **by name** but **not by value**.  
+  This is because queries are generally [based on indexes](../../start/getting-started#example-iii---querying), and Counter values are [not indexed](../../document-extensions/counters/counters-and-other-features#counters-and-indexing).  
+* Counter values **can** be [projected](../../indexes/querying/projections) from query results, as demonstrated in the following examples.  
+  This way a client can get Counter values from a query without downloading whole documents.  
+
+* Use [Session.Query](../../client-api/session/querying/how-to-query#session.query) to code queries yourself.  
+   * **Returned Counter Value**: **Accumulated**  
+     A Counter's value is returned as a single sum, with no specification of the Counter's value on each node.
+     {CODE counters_region_query@DocumentExtensions\Counters\Counters.cs /}
+
+* Use [RawQuery](../../client-api/session/querying/how-to-query#session.advanced.rawquery) to send the server raw RQL expressions for execution.  
+   * You can use the `counter` method.  
+     **Returned Counter Value**: **Accumulated**
+
+  * You can use the `counterRaw` method.  
+     **Returned Counter Value**: **Distributed**  
+     A Counter's value is returned as a series of values, each maintained by one of the nodes.  
+      * It is not expected of you to use this in your application.  
+        Applications normally use the Counter's overall value, and very rarely refer to the value each node gives it.  
+      
+        
+    `counter` and `counterRaw` samples:  
+    {CODE-TABS}
+    {CODE-TAB:csharp:counter counters_region_rawqueries_counter@DocumentExtensions\Counters\Counters.cs /}
+    {CODE-TAB:csharp:counterRaw counters_region_rawqueries_counterRaw@DocumentExtensions\Counters\Counters.cs /}
+    {CODE-TABS/}
+
+---
+
+###Counters and Revisions  
+
+A [document revision](../../document-extensions/revisions/overview) stores all the document Counters' 
+names and values when the revision was created.  
+ 
+* **Stored Counter Values**: **Accumulated**  
+  A revision stores a Counter's value as a single sum, with no specification of the Counter's value on each node.  
+
+* Revisions-creation can be initiated by **Counter-name modification**.  
+   * When the Revisions feature is enabled, the creation or deletion of a Counter initiates the creation of a new document revision.  
+   * Counter **value** modifications do **not** cause the creation of new revisions.  
+
+---
+
+###Counters and Smuggler  
+
+[Smuggler](../../client-api/smuggler/what-is-smuggler) is a DocumentStore property, that can be used 
+to [export](../../client-api/smuggler/what-is-smuggler#databasesmugglerexportoptions) chosen 
+database items to an external file or to [import](../../client-api/smuggler/what-is-smuggler#databasesmugglerimportoptions) 
+database items from an existing file into the database.  
+
+* **Transferred Counter Value**: **Distributed**  
+  Smuggler transfers the entire series of values that the different nodes maintain for a Counter.  
+* To make Smuggler handle Counters, include `DatabaseItemType.Counters` in `OperateOnTypes`'s list of entities to import or export.  
+  {CODE smuggler_options@DocumentExtensions\Counters\Counters.cs /}
+
+---
+
+###Counters and Changes API
+
+[Changes API](../../client-api/changes/what-is-changes-api#changes-api) is a Push service, that can inform you of various changes on the Server, including [changes in Counter values](../../client-api/changes/how-to-subscribe-to-counter-changes#changes-api--how-to-subscribe-to-counter-changes).  
+You can target all Counters, or specify the ones you wish to follow.  
+
+* **Pushed Counter Value**: **Accumulated**  
+  `Changes API` methods return a Counter's value as a single sum, without specifying its value on each node.  
+* The service is initiated by **Counter Value Modification**.  
+
+---
+
+###Counters and Ongoing Tasks:
+
+Each [ongoing task](../../studio/database/tasks/ongoing-tasks/general-info) relates to Counters in its own way.  
+
+* **Counters** and the **Backup task**  
+    There are two [backup](../../studio/database/tasks/backup-task) types: **logical-backup** and **snapshot**.  
+    Both types store and restore **all** data, including Counters.  
+    Both types operate as an ongoing backup routine, with a pre-set time schedule.  
+    * Logical Backup:  
+      **Backed-up Counter values**: **Distributed**  
+      A logical backup is a higher-level implementation of [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler).  
+      As with Smuggler, Counters are backed-up and restored including their values on all nodes.  
+    * Snapshot:  
+      A snapshot stores all data and settings as a single binary image.
+      All components, including Counters, are restored to the exact same state they've been at during backup.  
+
+* **Counters** and the **External Replication task**  
+    The ongoing [external replication](../../studio/database/tasks/ongoing-tasks/external-replication-task) task replicates all data, including Counters.  
+    * **Replicated Counter Value**: **Distributed**  
+        Counters are replicated along with their values on all nodes.  
+    * Replication can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+
+* **Counters** and the **ETL task**  
+    [ETL](../../server/ongoing-tasks/etl/basics) is used to export data from RavenDB to an external (either Raven or SQL) database.  
+    * [SQL ETL](../../server/ongoing-tasks/etl/sql) is **not supported**.  
+      Counters cannot be exported to an SQL database over SQL ETL.  
+    * [RavenDB ETL](../../server/ongoing-tasks/etl/raven) **is supported**.  
+      Counters [are](../../server/ongoing-tasks/etl/raven#counters) exported over RavenDB ETL.  
+      * Export can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+      * **Exported Counter Value**: **Distributed**  
+        Counters are exported along with their values on all nodes.  
+      * Counters can be [exported using a script](../../server/ongoing-tasks/etl/raven#adding-counter-explicitly-in-a-script).  
+        **Default behavior**: When an ETL script is not provided, Counters are exported.  
+      
+* **Counters** and the **[Data Subscriptions](../../client-api/data-subscriptions/what-are-data-subscriptions#data-subscriptions) task**  
+    Data Subscriptions can be initiated by document changes, including those caused by **Counter Name updates**.  
+    Documents will **not** be delivered in reaction to Counter Value modification.  
+
+
+{NOTE: }
+###Counters and Other Features: Summary
+
+Use this table to find if and how various RavenDB features are triggered by Counters, 
+and how the various features handle Counter values.  
+
+* In the **Triggered By** column:  
+    * _Document Change_ - Feature is triggered by a Counter Name update.  
+    * _Countrer Value Modification_ - Feature is triggered by a Counter Value modification.  
+    * _Time Schedule_ - Feature is invoked by a pre-set time routine.  
+    * _No Trigger_ - Feature is executed manually, through the Studio or by a Client.  
+* In the **Counter Value** column:  
+    * _Accumulated_ - Counter Value is handled as a single accumulated sum.  
+    * _Distributed_ - Counter Value is handled as a series of values maintained by cluster nodes.  
+
+| **Feature** | **Triggered by** | **Counter Value** |
+|-------------|:-------------|:-------------|
+| [Indexing](../../document-extensions/counters/counters-and-other-features#counters-and-indexing) | _Document Change_ | doesn't handle values |
+| [LINQ Queries](../../document-extensions/counters/counters-and-other-features#counters-and-queries) | _No trigger_ | _Accumulated_ |
+| [Raw Queries](../../document-extensions/counters/counters-and-other-features#counters-and-queries) | _No trigger_ | `counter()` - _Accumulated_ <br> `counterRaw()` - _Distributed_ |
+| [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler) | _No trigger_ | _Distributed_ |
+| [Backup Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Time Schedule_ | _Distributed_ |
+| [RavenDB ETL Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_, <br> _Countrer Value Modification_ | _Distributed_ |

+
+###Including Counters  
+You can [include](../../client-api/how-to/handle-document-relationships#includes) Counters while loading a document.  
+An included Counter is retrieved in the same request as its owner-document and is held by the session, 
+so it can be immediately retrieved when needed with no additional remote calls.
+
+
+* **Including Counters when using [Session.Load](../../client-api/session/loading-entities#session--loading-entities)**:  
+    * Include a single Counter using `IncludeCounter`.  
+    * Include multiple Counters using `IncludeCounters`.  
+
+    `IncludeCounter` and `IncludeCounters` usage samples:  
+    {CODE-TABS}
+    {CODE-TAB:csharp:IncludeCounter counters_region_load_include1@DocumentExtensions\Counters\Counters.cs /}
+    {CODE-TAB:csharp:IncludeCounters counters_region_load_include2@DocumentExtensions\Counters\Counters.cs /}
+    {CODE-TABS/}
+
+* **Including Counters when using [Session.Query](../../client-api/session/querying/how-to-query#session.query)**:  
+    * Include a single Counter using `IncludeCounter`.  
+    * Include multiple Counters using `IncludeCounters`.

+
+###Counters Bulk-Insert  
+`store.BulkInsert` is RavenDB's high-performance data insertion operation.  
+Use its `CountersFor` interface's `Increment` method to add or update counters with great speed.  
+
+* Syntax  
+
+   * `CountersFor`
+       {CODE CountersFor-definition@DocumentExtensions\Counters\BulkInsert.cs /}
+
+        | Parameters | Type | Description |
+        |:-------------|:-------------|:-------------|
+        | `id` | `string` | Document ID |
+
+   *   `Increment`
+          {CODE Increment-definition@DocumentExtensions\Counters\BulkInsert.cs /}
+
+           | Parameters | Type | Description |
+           |:-------------|:-------------|:-------------|
+           | `name` | `string` | Counter Name |
+           | `delta` | `long` | Default: 1L |
+
+* Usage Flow  
+
+   * Create a `store.BulkInsert` instance.  
+   * Pass the instance's `CountersFor` interface, the document ID  
+   * Call `Increment` as many times as you like. Pass it -  
+     The Counter Name and Value (delta to be added).
+
+* Usage Sample  
+  In this sample, we attach a counter to all User documents.

+  This is because queries are generally [based on indexes](../../start/getting-started#example-iii---querying), and Counter values are [not indexed](../../document-extensions/counters/counters-and-other-features#counters-and-indexing).  
+* Counter values **can** be projected from query results, as demonstrated in the following examples.  
+  This way a client can get Counter values from a query without downloading whole documents.  
+
+* Use `Session.Query` to code queries yourself.  
+   * **Returned Counter Value**: **Accumulated**  
+     A Counter's value is returned as a single sum, with no specification of the Counter's value on each node.
+     {CODE counters_region_query@DocumentExtensions\Counters\Counters.cs /}
+
+* Use `rawQuery` to send the server raw RQL expressions for execution.  
+   * You can use the `counter` method.  
+     **Returned Counter Value**: **Accumulated**
+
+  * You can use the `counterRaw` method.  
+     **Returned Counter Value**: **Distributed**  
+     A Counter's value is returned as a series of values, each maintained by one of the nodes.  
+      * It is not expected of you to use this in your application.  
+        Applications normally use the Counter's overall value, and very rarely refer to the value each node gives it.  
+      
+        
+    `counter` and `counterRaw` samples:

+
+###Counters and Revisions  
+
+A [document revision](../../document-extensions/revisions/overview) stores all the document Counters' 
+names and values when the revision was created.  
+ 
+* **Stored Counter Values**: **Accumulated**  
+  A revision stores a Counter's value as a single sum, with no specification of the Counter's value on each node.  
+
+* Revisions-creation can be initiated by **Counter-name modification**.  
+   * When the Revisions feature is enabled, the creation or deletion of a Counter initiates the creation of a new document revision.  
+   * Counter **value** modifications do **not** cause the creation of new revisions.  
+
+---
+
+###Counters and Smuggler  
+
+`Smuggler` is a DocumentStore property, that can be used 
+to **export** chosen database items to an external file or to 
+**import** database items from an existing file into the database.  
+
+* **Transferred Counter Value**: **Distributed**  
+  Smuggler transfers the entire series of values that the different nodes maintain for a Counter.  
+* To make Smuggler handle Counters, include `DatabaseItemType.COUNTERS` in `OperateOnTypes`'s list of entities to import or export.  
+  {CODE:java smuggler_options@DocumentExtensions\Counters\Counters.java /}
+
+---
+
+###Counters and Changes API
+
+[Changes API](../../client-api/changes/what-is-changes-api#changes-api) is a Push service, that can inform you of various changes on the Server, including [changes in Counter values](../../client-api/changes/how-to-subscribe-to-counter-changes#changes-api--how-to-subscribe-to-counter-changes).  
+You can target all Counters, or specify the ones you wish to follow.  
+
+* **Pushed Counter Value**: **Accumulated**  
+  `Changes API` methods return a Counter's value as a single sum, without specifying its value on each node.  
+* The service is initiated by **Counter Value Modification**.  
+
+---
+
+###Counters and Ongoing Tasks:
+
+Each [ongoing task](../../studio/database/tasks/ongoing-tasks/general-info) relates to Counters in its own way.  
+
+* **Counters** and the **Backup task**  
+    There are two backup types: **logical-backup** and **snapshot**.  
+    Both types store and restore **all** data, including Counters.  
+    Both types operate as an ongoing backup routine, with a pre-set time schedule.  
+    * Logical Backup:  
+      **Backed-up Counter values**: **Distributed**  
+      A logical backup is a higher-level implementation of [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler).  
+      As with Smuggler, Counters are backed-up and restored including their values on all nodes.  
+    * Snapshot:  
+      A snapshot stores all data and settings as a single binary image.
+      All components, including Counters, are restored to the exact same state they've been at during backup.  
+
+* **Counters** and the **External Replication task**  
+    The ongoing [external replication](../../studio/database/tasks/ongoing-tasks/external-replication-task) task replicates all data, including Counters.  
+    * **Replicated Counter Value**: **Distributed**  
+        Counters are replicated along with their values on all nodes.  
+    * Replication can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+
+* **Counters** and the **ETL task**  
+    [ETL](../../server/ongoing-tasks/etl/basics) is used to export data from RavenDB to an external (either Raven or SQL) database.  
+    * [SQL ETL](../../server/ongoing-tasks/etl/sql) is **not supported**.  
+      Counters cannot be exported to an SQL database over SQL ETL.  
+    * [RavenDB ETL](../../server/ongoing-tasks/etl/raven) **is supported**.  
+      Counters [are](../../server/ongoing-tasks/etl/raven#counters) exported over RavenDB ETL.  
+      * Export can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+      * **Exported Counter Value**: **Distributed**  
+        Counters are exported along with their values on all nodes.  
+      * Counters can be [exported using a script](../../server/ongoing-tasks/etl/raven#adding-counter-explicitly-in-a-script).  
+        **Default behavior**: When an ETL script is not provided, Counters are exported.  
+      
+* **Counters** and the **[Data Subscriptions](../../client-api/data-subscriptions/what-are-data-subscriptions#data-subscriptions) task**  
+    Data Subscriptions can be initiated by document changes, including those caused by **Counter Name updates**.  
+    Documents will **not** be delivered in reaction to Counter Value modification.  
+
+
+{NOTE: }
+###Counters and Other Features: Summary
+
+Use this table to find if and how various RavenDB features are triggered by Counters, 
+and how the various features handle Counter values.  
+
+* In the **Triggered By** column:  
+    * _Document Change_ - Feature is triggered by a Counter Name update.  
+    * _Countrer Value Modification_ - Feature is triggered by a Counter Value modification.  
+    * _Time Schedule_ - Feature is invoked by a pre-set time routine.  
+    * _No Trigger_ - Feature is executed manually, through the Studio or by a Client.  
+* In the **Counter Value** column:  
+    * _Accumulated_ - Counter Value is handled as a single accumulated sum.  
+    * _Distributed_ - Counter Value is handled as a series of values maintained by cluster nodes.  
+
+| **Feature** | **Triggered by** | **Counter Value** |
+|-------------|:-------------|:-------------|
+| [Indexing](../../document-extensions/counters/counters-and-other-features#counters-and-indexing) | _Document Change_ | doesn't handle values |

+###Including Counters  
+You can `include` Counters while loading a document.  
+An included Counter is retrieved in the same request as its owner-document and is 
+held by the session, so it can be immediately retrieved when needed with no additional 
+remote calls.
+
+* **Including Counters when using `Session.load`**:  
+    * Include a single Counter using `includeCounter`.  
+    * Include multiple Counters using `includeCounters`.  
+
+    `includeCounter` and `includeCounters` usage samples:  
+    {CODE-TABS}
+    {CODE-TAB:java:IncludeCounter counters_region_load_include1@DocumentExtensions\Counters\Counters.java /}
+    {CODE-TAB:java:IncludeCounters counters_region_load_include2@DocumentExtensions\Counters\Counters.java /}
+    {CODE-TABS/}
+
+* **Including Counters when using `Session.query`**:  
+    * Include a single Counter using `includeCounter`.  
+    * Include multiple Counters using `includeCounters`.

+
+###Counters Bulk-Insert  
+`store.bulkInsert` is RavenDB's high-performance data insertion operation.  
+Use its `countersFor` interface's `increment` method to add or update counters with great speed.  
+
+* Syntax  
+
+   * `countersFor`
+       {CODE:java CountersFor-definition@DocumentExtensions\Counters\Counters.java /}
+
+        | Parameters | Type | Description |
+        |:-------------|:-------------|:-------------|
+        | `id` | `String` | Document ID |
+
+   *   `increment`
+          {CODE:java Increment-definition@DocumentExtensions\Counters\Counters.java /}
+
+           | Parameters | Type | Description |
+           |:-------------|:-------------|:-------------|
+           | `name` | `String` | Counter Name |
+           | `id` | `String` | Document ID |
+           | `delta` | `long` | Default: 1L |
+
+* Usage Flow  
+
+   * Create a `store.bulkInsert` instance.  
+   * Pass the instance's `countersFor` interface, the document ID  
+   * Call `increment` as many times as you like. Pass it -  
+     The Counter Name and Value (delta to be added).
+
+* Usage Sample  
+  In this sample, we attach a counter to all User documents.

+
+### Counters and Indexing  
+
+Indexing Counters can speed-up finding them and the documents that contain them.  
+
+* **Indexing Counter Values**
+    Dynamic indexes (aka auto-indexes) _cannot_ index counter values. To index counter values, 
+    create a static index that inherits from `AbstractCountersIndexCreationTask` ([see here](../../document-extensions/counters/indexing)).
+
+* **Indexing Counter Names**  
+    Re-indexing due to Counter-name modification is normally rare enough to pause no performance issues.  
+    To index a document's Counters by name, use [CounterNamesFor](../../document-extensions/counters/indexing#section-1).  
+
+---
+
+###Counters and Queries  
+
+Create queries **using code**, or send the server **raw queries** for execution.  
+
+* Either way, you can query Counters **by name** but **not by value**.  
+  This is because queries are generally [based on indexes](../../start/getting-started#example-iii---querying), and Counter values are [not indexed](../../document-extensions/counters/counters-and-other-features#counters-and-indexing).  
+* Counter values **can** be [projected](../../indexes/querying/projections) from query results, as demonstrated in the following examples.  
+  This way a client can get Counter values from a query without downloading whole documents.  
+
+* Use [Session.Query](../../client-api/session/querying/how-to-query#session.query) to code queries yourself.  
+   * **Returned Counter Value**: **Accumulated**  
+     A Counter's value is returned as a single sum, with no specification of the Counter's value on each node.
+     {CODE:nodejs counters_region_query@DocumentExtensions\counters\counters.js /}
+
+* Use [RawQuery](../../client-api/session/querying/how-to-query#session.advanced.rawquery) to send the server raw RQL expressions for execution.  
+   * You can use the `counter` method.  
+     **Returned Counter Value**: **Accumulated**
+
+  * You can use the `counterRaw` method.  
+     **Returned Counter Value**: **Distributed**  
+     A Counter's value is returned as a series of values, each maintained by one of the nodes.  
+      * It is not expected of you to use this in your application.  
+        Applications normally use the Counter's overall value, and very rarely refer to the value each node gives it.  
+      
+        
+    `counter` and `counterRaw` samples:  
+    {CODE-TABS}
+    {CODE-TAB:nodejs:counter counters_region_rawqueries_counter@DocumentExtensions\counters\counters.js /}
+    {CODE-TAB:nodejs:counterRaw counters_region_rawqueries_counterRaw@DocumentExtensions\counters\counters.js /}
+    {CODE-TABS/}
+
+---
+
+###Counters and Revisions  
+
+A [document revision](../../document-extensions/revisions/overview) stores all the document Counters' 
+names and values when the revision was created.  
+ 
+* **Stored Counter Values**: **Accumulated**  
+  A revision stores a Counter's value as a single sum, with no specification of the Counter's value on each node.  
+
+* Revisions-creation can be initiated by **Counter-name modification**.  
+   * When the Revisions feature is enabled, the creation or deletion of a Counter initiates the creation of a new document revision.  
+   * Counter **value** modifications do **not** cause the creation of new revisions.  
+
+---
+
+###Counters and Smuggler  
+
+[Smuggler](../../client-api/smuggler/what-is-smuggler) is a DocumentStore property, that can be used 
+to [export](../../client-api/smuggler/what-is-smuggler#databasesmugglerexportoptions) chosen 
+database items to an external file or to [import](../../client-api/smuggler/what-is-smuggler#databasesmugglerimportoptions) 
+database items from an existing file into the database.  
+
+* **Transferred Counter Value**: **Distributed**  
+  Smuggler transfers the entire series of values that the different nodes maintain for a Counter.  
+* To make Smuggler handle Counters, use `DatabaseItemType` entities to import or export.  
+
+`DatabaseItemType` options:  
+* `None`  
+* `Documents`  
+* `RevisionDocuments`  
+* `Indexes`  
+* `Identities`  
+* `Tombstones`  
+* `LegacyAttachments`  
+* `Conflicts`  
+* `CompareExchange`  
+* `LegacyDocumentDeletions`  
+* `LegacyAttachmentDeletions`  
+* `DatabaseRecord`  
+* `Unknown`  
+* `Attachments`  
+* `CounterGroups`  
+* `Subscriptions`  
+* `CompareExchangeTombstones`  
+* `TimeSeries`  
+
+---
+
+###Counters and Changes API
+
+[Changes API](../../client-api/changes/what-is-changes-api#changes-api) is a Push service, that can inform you of various changes on the Server, including [changes in Counter values](../../client-api/changes/how-to-subscribe-to-counter-changes#changes-api--how-to-subscribe-to-counter-changes).  
+You can target all Counters, or specify the ones you wish to follow.  
+
+* **Pushed Counter Value**: **Accumulated**  
+  `Changes API` methods return a Counter's value as a single sum, without specifying its value on each node.  
+* The service is initiated by **Counter Value Modification**.  
+
+---
+
+###Counters and Ongoing Tasks:
+
+Each [ongoing task](../../studio/database/tasks/ongoing-tasks/general-info) relates to Counters in its own way.  
+
+* **Counters** and the **Backup task**  
+    There are two [backup](../../studio/database/tasks/backup-task) types: **logical-backup** and **snapshot**.  
+    Both types store and restore **all** data, including Counters.  
+    Both types operate as an ongoing backup routine, with a pre-set time schedule.  
+    * Logical Backup:  
+      **Backed-up Counter values**: **Distributed**  
+      A logical backup is a higher-level implementation of [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler).  
+      As with Smuggler, Counters are backed-up and restored including their values on all nodes.  
+    * Snapshot:  
+      A snapshot stores all data and settings as a single binary image.
+      All components, including Counters, are restored to the exact same state they've been at during backup.  
+
+* **Counters** and the **External Replication task**  
+    The ongoing [external replication](../../studio/database/tasks/ongoing-tasks/external-replication-task) task replicates all data, including Counters.  
+    * **Replicated Counter Value**: **Distributed**  
+        Counters are replicated along with their values on all nodes.  
+    * Replication can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+
+* **Counters** and the **ETL task**  
+    [ETL](../../server/ongoing-tasks/etl/basics) is used to export data from RavenDB to an external (either Raven or SQL) database.  
+    * [SQL ETL](../../server/ongoing-tasks/etl/sql) is **not supported**.  
+      Counters cannot be exported to an SQL database over SQL ETL.  
+    * [RavenDB ETL](../../server/ongoing-tasks/etl/raven) **is supported**.  
+      Counters [are](../../server/ongoing-tasks/etl/raven#counters) exported over RavenDB ETL.  
+      * Export can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+      * **Exported Counter Value**: **Distributed**  
+        Counters are exported along with their values on all nodes.  
+      * Counters can be [exported using a script](../../server/ongoing-tasks/etl/raven#adding-counter-explicitly-in-a-script).  
+        **Default behavior**: When an ETL script is not provided, Counters are exported.  
+      
+* **Counters** and the **[Data Subscriptions](../../client-api/data-subscriptions/what-are-data-subscriptions#data-subscriptions) task**  
+    Data Subscriptions can be initiated by document changes, including those caused by **Counter Name updates**.  
+    Documents will **not** be delivered in reaction to Counter Value modification.  
+
+
+{NOTE: }
+###Counters and Other Features: Summary
+
+Use this table to find if and how various RavenDB features are triggered by Counters, 
+and how the various features handle Counter values.  
+
+* In the **Triggered By** column:  
+    * _Document Change_ - Feature is triggered by a Counter Name update.  
+    * _Countrer Value Modification_ - Feature is triggered by a Counter Value modification.  
+    * _Time Schedule_ - Feature is invoked by a pre-set time routine.  
+    * _No Trigger_ - Feature is executed manually, through the Studio or by a Client.  
+* In the **Counter Value** column:  
+    * _Accumulated_ - Counter Value is handled as a single accumulated sum.  
+    * _Distributed_ - Counter Value is handled as a series of values maintained by cluster nodes.  
+
+| **Feature** | **Triggered by** | **Counter Value** |
+|-------------|:-------------|:-------------|

+
+### Counters and Indexing  
+
+Indexing Counters can speed-up finding them and the documents that contain them.  
+
+* **Indexing Counter Values**
+    Dynamic indexes (aka auto-indexes) _cannot_ index counter values. To index counter values, 
+    create a static index that inherits from `AbstractCountersIndexCreationTask` ([see here](../../document-extensions/counters/indexing)).
+
+* **Indexing Counter Names**  
+    Re-indexing due to Counter-name modification is normally rare enough to pause no performance issues.  
+    To index a document's Counters by name, use [CounterNamesFor](../../document-extensions/counters/indexing#section-1).  
+
+---
+
+###Counters and Queries  
+
+Create queries **using code**, or send the server **raw queries** for execution.  
+
+* Either way, you can query Counters **by name** but **not by value**.  
+  This is because queries are generally [based on indexes](../../start/getting-started#example-iii---querying), and Counter values are [not indexed](../../document-extensions/counters/counters-and-other-features#counters-and-indexing).  
+* Counter values **can** be [projected](../../indexes/querying/projections) from query results, as demonstrated in the following examples.  
+  This way a client can get Counter values from a query without downloading whole documents.  
+
+* Use [session.query](../../client-api/session/querying/how-to-query#session.query) to code queries yourself.  
+   * **Returned Counter Value**: **Accumulated**  
+     A Counter's value is returned as a single sum, with no specification of the Counter's value on each node.
+     {CODE:python counters_region_query@DocumentExtensions\Counters\Counters.py /}
+
+* Use [RawQuery](../../client-api/session/querying/how-to-query#session.advanced.rawquery) to send the server raw RQL expressions for execution.  
+   * You can use the `counter` method.  
+     **Returned Counter Value**: **Accumulated**
+
+  * You can use the `counterRaw` method.  
+     **Returned Counter Value**: **Distributed**  
+     A Counter's value is returned as a series of values, each maintained by one of the nodes.  
+      * It is not expected of you to use this in your application.  
+        Applications normally use the Counter's overall value, and very rarely refer to the value each node gives it.  
+      
+        
+    `counter` and `counterRaw` samples:  
+    {CODE-TABS}
+    {CODE-TAB:python:counter counters_region_rawqueries_counter@DocumentExtensions\Counters\Counters.py /}
+    {CODE-TAB:python:counterRaw counters_region_rawqueries_counterRaw@DocumentExtensions\Counters\Counters.py /}
+    {CODE-TABS/}
+
+---
+
+###Counters and Revisions  
+
+A [document revision](../../document-extensions/revisions/overview) stores all the document Counters' 
+names and values when the revision was created.  
+ 
+* **Stored Counter Values**: **Accumulated**  
+  A revision stores a Counter's value as a single sum, with no specification of the Counter's value on each node.  
+
+* Revisions-creation can be initiated by **Counter-name modification**.  
+   * When the Revisions feature is enabled, the creation or deletion of a Counter initiates the creation of a new document revision.  
+   * Counter **value** modifications do **not** cause the creation of new revisions.  
+
+---
+
+###Counters and Changes API
+
+[Changes API](../../client-api/changes/what-is-changes-api#changes-api) is a Push service, that can inform you of various changes on the Server, including [changes in Counter values](../../client-api/changes/how-to-subscribe-to-counter-changes#changes-api--how-to-subscribe-to-counter-changes).  
+You can target all Counters, or specify the ones you wish to follow.  
+
+* **Pushed Counter Value**: **Accumulated**  
+  `Changes API` methods return a Counter's value as a single sum, without specifying its value on each node.  
+* The service is initiated by **Counter Value Modification**.  
+
+---
+
+###Counters and Ongoing Tasks:
+
+Each [ongoing task](../../studio/database/tasks/ongoing-tasks/general-info) relates to Counters in its own way.  
+
+* **Counters** and the **Backup task**  
+    There are two [backup](../../studio/database/tasks/backup-task) types: **logical-backup** and **snapshot**.  
+    Both types store and restore **all** data, including Counters.  
+    Both types operate as an ongoing backup routine, with a pre-set time schedule.  
+    * Logical Backup:  
+      **Backed-up Counter values**: **Distributed**  
+      A logical backup is a higher-level implementation of [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler).  
+      As with Smuggler, Counters are backed-up and restored including their values on all nodes.  
+    * Snapshot:  
+      A snapshot stores all data and settings as a single binary image.
+      All components, including Counters, are restored to the exact same state they've been at during backup.  
+
+* **Counters** and the **External Replication task**  
+    The ongoing [external replication](../../studio/database/tasks/ongoing-tasks/external-replication-task) task replicates all data, including Counters.  
+    * **Replicated Counter Value**: **Distributed**  
+        Counters are replicated along with their values on all nodes.  
+    * Replication can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+
+* **Counters** and the **ETL task**  
+    [ETL](../../server/ongoing-tasks/etl/basics) is used to export data from RavenDB to an external (either Raven or SQL) database.  
+    * [SQL ETL](../../server/ongoing-tasks/etl/sql) is **not supported**.  
+      Counters cannot be exported to an SQL database over SQL ETL.  
+    * [RavenDB ETL](../../server/ongoing-tasks/etl/raven) **is supported**.  
+      Counters [are](../../server/ongoing-tasks/etl/raven#counters) exported over RavenDB ETL.  
+      * Export can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+      * **Exported Counter Value**: **Distributed**  
+        Counters are exported along with their values on all nodes.  
+      * Counters can be [exported using a script](../../server/ongoing-tasks/etl/raven#adding-counter-explicitly-in-a-script).  
+        **Default behavior**: When an ETL script is not provided, Counters are exported.  
+      
+* **Counters** and the **[Data Subscriptions](../../client-api/data-subscriptions/what-are-data-subscriptions#data-subscriptions) task**  
+    Data Subscriptions can be initiated by document changes, including those caused by **Counter Name updates**.  
+    Documents will **not** be delivered in reaction to Counter Value modification.  
+
+
+{NOTE: }
+###Counters and Other Features: Summary
+
+Use this table to find if and how various RavenDB features are triggered by Counters, 
+and how the various features handle Counter values.  
+
+* In the **Triggered By** column:  
+    * _Document Change_ - Feature is triggered by a Counter Name update.  
+    * _Countrer Value Modification_ - Feature is triggered by a Counter Value modification.  
+    * _Time Schedule_ - Feature is invoked by a pre-set time routine.  
+    * _No Trigger_ - Feature is executed manually, through the Studio or by a Client.  
+* In the **Counter Value** column:  
+    * _Accumulated_ - Counter Value is handled as a single accumulated sum.  
+    * _Distributed_ - Counter Value is handled as a series of values maintained by cluster nodes.  
+
+| **Feature** | **Triggered by** | **Counter Value** |
+|-------------|:-------------|:-------------|
+| [Indexing](../../document-extensions/counters/counters-and-other-features#counters-and-indexing) | _Document Change_ | doesn't handle values |
+| [LINQ Queries](../../document-extensions/counters/counters-and-other-features#counters-and-queries) | _No trigger_ | _Accumulated_ |
+| [Raw Queries](../../document-extensions/counters/counters-and-other-features#counters-and-queries) | _No trigger_ | `counter()` - _Accumulated_ <br> `counterRaw()` - _Distributed_ |
+| [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler) | _No trigger_ | _Distributed_ |
+| [Backup Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Time Schedule_ | _Distributed_ |
+| [RavenDB ETL Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_, <br> _Countrer Value Modification_ | _Distributed_ |
+| [External Replication task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_, <br> _Countrer Value Modification_ | _Distributed_ |
+| [Data Subscriptions Update Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_ | |
+| [Changes API](../../document-extensions/counters/counters-and-other-features#counters-and-changes-api) | _Countrer Value Modification_ | _Accumulated_ |
+| [Revision creation](../../document-extensions/counters/counters-and-other-features#counters-and-revisions) | _Document Change_ | _Accumulated_ |

+###Including Counters  
+You can [include](../../client-api/how-to/handle-document-relationships#includes) Counters while loading a document.  
+An included Counter is retrieved in the same request as its owner-document and is held by the session, 
+so it can be immediately retrieved when needed with no additional remote calls.
+
+
+* **Including Counters when using [session.load](../../client-api/session/loading-entities#session--loading-entities)**:  
+    * Include a single Counter using `include_counter`  
+    * Include multiple Counters using `include_counters`  
+
+    `include_counter` and `include_counters` usage samples:  
+    {CODE-TABS}

+    {CODE-TABS/}
+
+* **Including Counters when using [Session.Query](../../client-api/session/querying/how-to-query#session--querying--how-to-query)**:  
+    * Include a single Counter using `include_counter`.  
+    * Include multiple Counters using `include_counters`.

+# Counters Overview
+
+
+{NOTE: }
+
+* RavenDB's distributed counters, **Counters** for short, are numeric data variables that can be added to documents. 
+  Use a Counter to count anything that needs counting, like:
+   * Sold products  
+   * Voting results  
+   * Any event related to the document  
+   
+* Counters interact with and can trigger other RavenDB features.  
+ To find out how to use counters with other features, read [Counters and Other Features](../../../csharp/document-extensions/counters/counters-and-other-features).  
+
+* Create and manage Counters using API methods, or through the [Studio](../../studio/database/document-extensions/counters).  
+
+* In this page:  
+  * [Why use Counters?](../../document-extensions/counters/overview#why-use-counters?)  
+  * [Overview](../../document-extensions/counters/overview#overview)  
+  * [Managing Counters](../../document-extensions/counters/overview#managing-counters)

+{NOTE/}
+

+
+{PANEL: Why use Counters?}
+
+#### Convenient Counting Mechanism
+
+Counters are very easy to manage, using simple API methods or through the Studio.  
+
+E.g. Use counters when you want to -  
+
+- Keep track of the number of times a document has been viewed or rated.  
+- Count how many visitors from certain countries or regions read a document.  
+- Continuously record the number of visitors on an event page.  
+- Avoid having to update the whole document for just a numeric value change.  
+- Have a need for a high-throughput counter (also see **Distributed Values** below).  
+
+---
+
+#### Distributed Values
+
+A Counter's value is [distributed between cluster nodes](../../document-extensions/counters/counters-in-clusters).  
+Among the advantages of this:  
+
+* The cluster **remains available** even when nodes crash.  
+* Any node can provide or modify a Counter's value immediately, without checking or coordinating this with other nodes.  
+
+---
+
+#### High Performance, Low Resources
+
+A document includes the Counter's _name_, while the Counter's actual _value_ is kept in a separate location.  
+Modifying a Counter's value doesn't require the modification of the document itself.  
+This results in highly efficient operation.
+
+---
+
+#### High-Frequency Counting
+
+Counters are especially useful when a very large number of counting operations is required,  
+because of their speed and low resources usage.  
+
+E.g. Use Counters - 
+
+- For an online election page, to continuously update a Number-Of-Votes Counter for each candidate.  
+- To continuously update Counters with the number of visitors in different sections of a big online store.  
+
+{PANEL/}
+
+{PANEL: Overview}
+
+#### Design
+
+A document's metadata contains only the ***Counters' names-list*** for this document.  
+***Counter Values*** are not kept in the document's metadata, but in a separate location.  
+
+Therefore, changes like adding a new counter or deleting an existing counter trigger a document change,  
+while simply modifying the Counter Value does not.  
+
+---
+
+#### Cumulative Counter Actions
+
+* Counter value-modification actions are cumulative, the order in which they are executed doesn't matter.  
+  E.g., It doesn't matter if a Counter has been incremented by 2 and then by 7, or by 7 first and then by 2.  
+
+* When a Counter is deleted, the sequence of Counter actions becomes non-cumulative and may require 
+  [special attention](../../document-extensions/counters/counters-in-clusters#concurrent-delete-and-increment).  
+
+---
+
+#### Counters and Conflicts
+
+Counter actions (for either name or value) almost never cause conflicts.  
+The only exception to this is [concurrent `delete` and `increment`](../../document-extensions/counters/counters-in-clusters#concurrent-delete-and-increment) 
+actions by multiple cluster nodes.  
+
+- Counter actions can be executed concurrently or in any order, without causing a conflict.  
+- You can successfully modify Counters while their document is being modified by a different client.  
+
+{NOTE: }
+Counter actions **can still be performed** when their related documents are in a conflicted state.  
+{NOTE/}
+
+---
+
+#### Counters Cost
+
+Counters are designated to lower the cost of counting, but do come with a price.  
+
+* **All the names** of a document's Counters are added to its content, increasing its size.  
+* **Counter values** occupy storage space.  
+
+{NOTE: }
+Be aware that the negligible amount of resources required by a few Counters, 
+may become significant when there are many.  
+A single document with thousands of Counters is probably an indication of a modeling mistake, 
+for example.  
+{NOTE/}
+
+---
+
+#### Counters Naming Convention
+
+* Valid characters: All visible characters, [including Unicode symbols](../../studio/database/document-extensions/counters#section)  
+* Length: Up to 512 bytes  
+* Encoding: UTF-8  
+
+---
+
+#### Counter Values
+
+* Valid range: Signed 64-bit integer (-9223372036854775808 to 9223372036854775807)  
+* Only integer additions are supported (no floats or other mathematical operations).
+
+---
+
+#### Number of Counters Per Document
+
+RavenDB doesn't limit the number of Counters you can create.  
+
+{NOTE: }
+Note that the Counter names are stored in the document metadata and [do impact the size of the document](../../document-extensions/counters/overview#counters-cost).  
+{NOTE/}
+
+---
+
+#### The `HasCounters` Flag
+
+When a Counter is added to a document, RavenDB automatically sets a `HasCounters` Flag in the document's metadata.  
+When all Counters are removed from a document, the server automatically removes this flag.  
+
+{PANEL/}
+
+{PANEL: Managing Counters}
+
+#### Counter Methods and the `counters_for` Object
+
+Managing Counters is performed using the `counters_for` session object.  
+
+*  **Counter methods**: 
+ 
+ | Method                  | Description                                                                             |
+ |-------------------------|-----------------------------------------------------------------------------------------|
+ | `counters_for.increment` | Increment the value of an existing Counter, or create a new Counter if it doesn't exist |
+ | `counters_for.delete`    | Delete a Counter                                                                        |
+ | `counters_for.get`       | Get the current value of a Counter                                                      |
+ | `counters_for.get_all`    | Get *all* the Counters of a document and their values                                   |
+
+
+* **Usage flow**:  
+  * Open a session.  
+  * Create an instance of `counters_for`.  
+      * Either pass `counters_for` an explicit document ID, -or-  
+      * Pass it an [entity tracked by the session](../../client-api/session/loading-entities), 
+        e.g. a document object returned from [session.query](../../client-api/session/querying/how-to-query) or from [session.load](../../client-api/session/loading-entities#load).  
+  * Use Counter methods to manage the document's Counters.  
+  * If you execute [increment](../../document-extensions/counters/create-or-modify) or [delete](../../document-extensions/counters/delete), call `session.save_changes` for the action to take effect on the server.  
+
+* **Success and failure**:  
+  * As long as the document exists, Counter actions (Increment, Get, Delete etc.) always succeed.
+  * When a transaction that includes a Counter modification fails for any reason (e.g. a document concurrency conflict),  
+    the Counter modification is reverted.
+
+* **`counters_for` usage samples**:  
+  * You can Use `counters_for` by **explicitly passing it a document ID** (without pre-loading the document).  
+  * You can also use `counters_for` by passing it **the document object**.  
+  
+  {CODE-TABS}
+  {CODE-TAB:python:Pass-CountersFor-Document-ID counters_region_CountersFor_without_document_load@DocumentExtensions\Counters\Counters.py /}
+  {CODE-TAB:python:Pass-CountersFor-Document-Object counters_region_CountersFor_with_document_load@DocumentExtensions\Counters\Counters.py /}
+  {CODE-TABS/}
+
+---
+
+#### Managing Counters using `Operations`
+
+* In addition to working with the high-level Session, you can manage Counters using the low-level [Operations](../../client-api/operations/what-are-operations).  
+
+* [CounterBatchOperation](../../client-api/operations/counters/counter-batch) 
+can operate on a set of Counters of different documents in a single request.

+
+### Counters and Indexing  
+
+Indexing Counters can speed-up finding them and the documents that contain them.  
+
+* **Indexing Counter Values**
+    Dynamic indexes (aka auto-indexes) _cannot_ index counter values. To index counter values, 
+    create a static index that inherits from `AbstractCountersIndexCreationTask` ([see here](../../document-extensions/counters/indexing)).
+
+* **Indexing Counter Names**  
+    Re-indexing due to Counter-name modification is normally rare enough to pause no performance issues.  
+    To index a document's Counters by name, use [CounterNamesFor](../../document-extensions/counters/indexing#section-1).  
+
+---
+
+###Counters and Queries  
+
+Create queries **using code**, or send the server **raw queries** for execution.  
+
+* Either way, you can query Counters **by name** but **not by value**.  
+  This is because queries are generally [based on indexes](../../start/getting-started#example-iii---querying), and Counter values are [not indexed](../../document-extensions/counters/counters-and-other-features#counters-and-indexing).  
+* Counter values **can** be [projected](../../indexes/querying/projections) from query results, as demonstrated in the following examples.  
+  This way a client can get Counter values from a query without downloading whole documents.  
+
+* Use [session.query](../../client-api/session/querying/how-to-query#session.query) to code queries yourself.  
+   * **Returned Counter Value**: **Accumulated**  
+     A Counter's value is returned as a single sum, with no specification of the Counter's value on each node.
+     {CODE:python counters_region_query@DocumentExtensions\Counters\Counters.py /}
+
+* Use [RawQuery](../../client-api/session/querying/how-to-query#session.advanced.rawquery) to send the server raw RQL expressions for execution.  
+   * You can use the `counter` method.  
+     **Returned Counter Value**: **Accumulated**
+
+  * You can use the `counterRaw` method.  
+     **Returned Counter Value**: **Distributed**  
+     A Counter's value is returned as a series of values, each maintained by one of the nodes.  
+      * It is not expected of you to use this in your application.  
+        Applications normally use the Counter's overall value, and very rarely refer to the value each node gives it.  
+      
+        
+    `counter` and `counterRaw` samples:  
+    {CODE-TABS}
+    {CODE-TAB:python:counter counters_region_rawqueries_counter@DocumentExtensions\Counters\Counters.py /}
+    {CODE-TAB:python:counterRaw counters_region_rawqueries_counterRaw@DocumentExtensions\Counters\Counters.py /}
+    {CODE-TABS/}
+
+---
+
+###Counters and Revisions  
+
+A [document revision](../../document-extensions/revisions/overview) stores all the document Counters' 
+names and values when the revision was created.  
+ 
+* **Stored Counter Values**: **Accumulated**  
+  A revision stores a Counter's value as a single sum, with no specification of the Counter's value on each node.  
+
+* Revisions-creation can be initiated by **Counter-name modification**.  
+   * When the Revisions feature is enabled, the creation or deletion of a Counter initiates the creation of a new document revision.  
+   * Counter **value** modifications do **not** cause the creation of new revisions.  
+
+---
+
+###Counters and Changes API
+
+[Changes API](../../client-api/changes/what-is-changes-api#changes-api) is a Push service, that can inform you of various changes on the Server, including [changes in Counter values](../../client-api/changes/how-to-subscribe-to-counter-changes#changes-api--how-to-subscribe-to-counter-changes).  
+You can target all Counters, or specify the ones you wish to follow.  
+
+* **Pushed Counter Value**: **Accumulated**  
+  `Changes API` methods return a Counter's value as a single sum, without specifying its value on each node.  
+* The service is initiated by **Counter Value Modification**.  
+
+---
+
+###Counters and Ongoing Tasks:
+
+Each [ongoing task](../../studio/database/tasks/ongoing-tasks/general-info) relates to Counters in its own way.  
+
+* **Counters** and the **Backup task**  
+    There are two [backup](../../studio/database/tasks/backup-task) types: **logical-backup** and **snapshot**.  
+    Both types store and restore **all** data, including Counters.  
+    Both types operate as an ongoing backup routine, with a pre-set time schedule.  
+    * Logical Backup:  
+      **Backed-up Counter values**: **Distributed**  
+      A logical backup is a higher-level implementation of [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler).  
+      As with Smuggler, Counters are backed-up and restored including their values on all nodes.  
+    * Snapshot:  
+      A snapshot stores all data and settings as a single binary image.
+      All components, including Counters, are restored to the exact same state they've been at during backup.  
+
+* **Counters** and the **External Replication task**  
+    The ongoing [external replication](../../studio/database/tasks/ongoing-tasks/external-replication-task) task replicates all data, including Counters.  
+    * **Replicated Counter Value**: **Distributed**  
+        Counters are replicated along with their values on all nodes.  
+    * Replication can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+
+* **Counters** and the **ETL task**  
+    [ETL](../../server/ongoing-tasks/etl/basics) is used to export data from RavenDB to an external (either Raven or SQL) database.  
+    * [SQL ETL](../../server/ongoing-tasks/etl/sql) is **not supported**.  
+      Counters cannot be exported to an SQL database over SQL ETL.  
+    * [RavenDB ETL](../../server/ongoing-tasks/etl/raven) **is supported**.  
+      Counters [are](../../server/ongoing-tasks/etl/raven#counters) exported over RavenDB ETL.  
+      * Export can be initiated by both **Counter-name update** _and_ **Counter-value modification**.  
+      * **Exported Counter Value**: **Distributed**  
+        Counters are exported along with their values on all nodes.  
+      * Counters can be [exported using a script](../../server/ongoing-tasks/etl/raven#adding-counter-explicitly-in-a-script).  
+        **Default behavior**: When an ETL script is not provided, Counters are exported.  
+      
+* **Counters** and the **[Data Subscriptions](../../client-api/data-subscriptions/what-are-data-subscriptions#data-subscriptions) task**  
+    Data Subscriptions can be initiated by document changes, including those caused by **Counter Name updates**.  
+    Documents will **not** be delivered in reaction to Counter Value modification.  
+
+
+{NOTE: }
+###Counters and Other Features: Summary
+
+Use this table to find if and how various RavenDB features are triggered by Counters, 
+and how the various features handle Counter values.  
+
+* In the **Triggered By** column:  
+    * _Document Change_ - Feature is triggered by a Counter Name update.  
+    * _Countrer Value Modification_ - Feature is triggered by a Counter Value modification.  
+    * _Time Schedule_ - Feature is invoked by a pre-set time routine.  
+    * _No Trigger_ - Feature is executed manually, through the Studio or by a Client.  
+* In the **Counter Value** column:  
+    * _Accumulated_ - Counter Value is handled as a single accumulated sum.  
+    * _Distributed_ - Counter Value is handled as a series of values maintained by cluster nodes.  
+
+| **Feature** | **Triggered by** | **Counter Value** |
+|-------------|:-------------|:-------------|
+| [Indexing](../../document-extensions/counters/counters-and-other-features#counters-and-indexing) | _Document Change_ | doesn't handle values |
+| [LINQ Queries](../../document-extensions/counters/counters-and-other-features#counters-and-queries) | _No trigger_ | _Accumulated_ |
+| [Raw Queries](../../document-extensions/counters/counters-and-other-features#counters-and-queries) | _No trigger_ | `counter()` - _Accumulated_ <br> `counterRaw()` - _Distributed_ |
+| [Smuggler](../../document-extensions/counters/counters-and-other-features#counters-and-smuggler) | _No trigger_ | _Distributed_ |
+| [Backup Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Time Schedule_ | _Distributed_ |
+| [RavenDB ETL Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_, <br> _Countrer Value Modification_ | _Distributed_ |
+| [External Replication task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_, <br> _Countrer Value Modification_ | _Distributed_ |
+| [Data Subscriptions Update Task](../../document-extensions/counters/counters-and-other-features#counters-and-ongoing-tasks) | _Document Change_ | |
+| [Changes API](../../document-extensions/counters/counters-and-other-features#counters-and-changes-api) | _Countrer Value Modification_ | _Accumulated_ |
+| [Revision creation](../../document-extensions/counters/counters-and-other-features#counters-and-revisions) | _Document Change_ | _Accumulated_ |

+
+###Including Counters  
+You can [include](../../client-api/how-to/handle-document-relationships#includes) Counters while loading a document.  
+An included Counter is retrieved in the same request as its owner-document and is held by the session, 
+so it can be immediately retrieved when needed with no additional remote calls.
+
+
+* **Including Counters when using [session.load](../../client-api/session/loading-entities#session--loading-entities)**:  
+    * Include a single Counter using `include_counter`  
+    * Include multiple Counters using `include_counters`  
+
+    `include_counter` and `include_counters` usage samples:  
+    {CODE-TABS}
+    {CODE-TAB:python:IncludeCounter counters_region_load_include1@DocumentExtensions\Counters\Counters.py /}
+    {CODE-TAB:python:IncludeCounters counters_region_load_include2@DocumentExtensions\Counters\Counters.py /}
+    {CODE-TABS/}
+
+* **Including Counters when using [Session.Query](../../client-api/session/querying/how-to-query#session--querying--how-to-query)**:  
+    * Include a single Counter using `include_counter`.  
+    * Include multiple Counters using `include_counters`.  
+
+    `include_counter` and `include_counters` usage samples:  
+    {CODE-TABS}

+###Counters Bulk-Insert  
+`store.bulk_insert` is RavenDB's high-performance data insertion operation.  
+Use its `counters_for` interface's `increment` method to add or update counters with great speed.  
+
+* Syntax  
+
+   * `counters_for`
+     {CODE:python CountersFor-definition@DocumentExtensions\Counters\BulkInsert.py /}
+
+       | Parameters | Type | Description |
+       |:-------------|:-------------|:-------------|
+       | **id** | `str` | Document ID |
+
+   * `Increment`
+     {CODE:python Increment-definition@DocumentExtensions\Counters\BulkInsert.py /}
+
+       | Parameters | Type | Description |
+       |:-------------|:-------------|:-------------|
+       | **name** | `str` | Counter Name |
+       | **delta** | `int` | Default: 1L |
+
+* Usage Flow  
+
+   * Create a `store.bulk_insert` instance.  
+   * Pass the instance's `counters_for` interface, the document ID  
+   * Call `increment` as many times as you like. Pass it -  
+     The Counter Name and Value (delta to be added).
+
+* Usage Sample  
+  In this sample, we attach a counter to all User documents.
