HTTP Protocol

OrientDB RESTful HTTP protocol allows to talk with a OrientDB Server instance using the HTTP protocol and JSON. OrientDB supports also a highly optimized Binary protocol for superior performances.

Available Commands

allocation DB's defragmentation	batch Batch of commands	class Operations on schema classes	cluster Operations on clusters
command Executes commands	connect Create the session	database Information about database	disconnect Disconnect session
document Operations on documents by RID GET - HEAD - POST - PUT - DELETE - PATCH	documentbyclass Operations on documents by Class	export Exports a database	function Executes a server-side function
index Operations on indexes	listDatabases Available databases	property Operations on schema properties	query Query
server Information about the server

HTTP Methods

This protocol uses the four methods of the HTTP protocol:

GET, to retrieve values from the database. It's idempotent that means no changes to the database happen. Remember that in IE6 the URL can be maximum of 2,083 characters. Other browsers supports longer URLs, but if you want to stay compatible with all limit to 2,083 characters
POST, to insert values into the database
PUT, to change values into the database
DELETE, to delete values from the database

When using POST and PUT the following are important when preparing the contents of the post message:

Always have the content type set to “application/json” or "application/xml"
Where data or data structure is involved the content is in JSON format
For OrientDB SQL or Gremlin the content itself is just text

Headers

All the requests must have these 2 headers:

'Accept-Encoding': 'gzip,deflate'
'Content-Length': <content-length>

Where the <content-length> is the length of the request's body.

Syntax

The REST API is very flexible, with the following features:

Data returned is in JSON format
JSONP callback is supported
Support for http and https connections
The API itself is case insensitive
API can just be used as a wrapper to retrieve (and control) data through requests written in OrientDB SQL or Gremlin
You can avoid using # for RecordIDs in URLs, if you prefer. Just drop the # from the URL and it will still work

The REST syntax used is the same for all the four HTTP methods:

Syntax: http://<server>:<port>/<command>/[<database>/<arguments>]

Results are always in JSON format. Support for 'document' object types is through the use of the attribute @type : 'd'. This also applies when using inner document objects. Example:

{
  "@type"  : "d",
  "Name"   : "Test",
  "Data"   : { "@type": "d",
               "value": 0 },
  "@class" : "SimpleEntity"
}

JSONP is also supported by adding a callback parameter to the request (containing the callback function name).

Syntax: http://<server>:<port>/<command>/[<database>/<arguments>]?callback=<callbackFunctionName>

Commands are divided in two main categories:

Server commands, such as to know server statistics and to create a new database
Database commands, all the commands against a database

Authentication and security

All the commands (but the Disconnect need a valid authentication before to get executed. The OrientDB Server checks if the Authorization HTTP header is present, otherwise answers with a request of authentication (HTTP error code: 401).

The HTTP client (or the Internet Browser) must send user and password using the HTTP Base authentication. Password is encoded using Base64 algorithm. Please note that if you want to encrypt the password using a safe mode take in consideration to use SSL connections.

Server commands use the realm "OrientDB Server", while the database commands use a realm per database in this form: "OrientDB db-<database>", where <database> is the database name. In this way the Browser/HTTP client can reuse user and password inserted multiple times until the session expires or the "Disconnect" is called.

On first call (or when the session is expired and a new authentication is required), OrientDB returns the OSESSIONID parameter in response's HTTP header. On further calls the client should pass this OSESSIONID header in the requests and OrientDB will skip the authentication because a session is alive. By default sessions expire after 300 seconds (5 minutes), but you can change this configuration by setting the global setting: network.http.sessionExpireTimeout

JSON data type handling and Schema-less mode

Since OrientDB supports also schema-less/hybrid modes how to manage types? JSON doesn't support all the types OrientDB has, so how can I pass the right type when it's not defined in the schema?

The answer is using the special field "@fieldTypes" as string containing all the field types separated by comma. Example:

{ "@class":"Account", "date": 1350426789, "amount": 100.34,
  "@fieldTypes": "date=t,amount=c" }

The supported special types are:

'f' for float
'c' for decimal
'l' for long
'd' for double
'b' for byte and binary
'a' for date
't' for datetime
's' for short
'e' for Set, because arrays and List are serialized as arrays like [3,4,5]
'x' for links
'n' for linksets
'z' for linklist
'm' for linkmap
'g' for linkbag
'u' for custom

Keep-Alive

Attention: OrientDB HTTP API utilizes Keep-Alive feature for better performance: the TCP/IP socket is kept open avoiding the creation of a new one for each command. If you need to re-authenticate, open a new connection avoiding to reuse the already open one. To force closing put "Connection: close" in the request header.

      "linkedClass": "Person"
  }
...

HTTP response: 6

Cluster

GET - Cluster

Where the primary usage is a document db, or where the developer wants to optimise retrieval using the clustering of the database, use the CLUSTER command to browse the records of the requested cluster.

Syntax: http://<server>:[<port>]/cluster/<database>/<cluster-name>/

Where <limit> is optional and tells the maximum of records to load. Default is 20.

Example

HTTP GET request: http://localhost:2480/cluster/demo/Address

HTTP response:

{ "schema": {
    "id": 5,
    "name": "Address"
  },
  "result": [{
      "_id": "11:0",
      "_ver": 0,
      "@class": "Address",
      "type": "Residence",
      "street": "Piazza Navona, 1",
      "city": "12:0"
    }
...

Command

POST - Command

Execute a command against the database. Returns the records affected or the list of records for queries. Command executed via POST can be non-idempotent (look at Query).

Syntax: http://<server>:[<port>]/command/<database>/<language>[/<command-text>[/limit[/<fetchPlan>]]]

The content can be <command-text> or starting from v2.2 a json containing the command and parameters:

by parameter name: {"command":<command-text>, "parameters":{"<param-name>":<param-value>} }
by parameter position: {"command":<command-text>, "parameters":[<param-value>] }

Where:

<language> is the name of the language between those supported. OrientDB distribution comes with "sql" and GraphDB distribution has both "sql" and "gremlin"
command-text is the text containing the command to execute
limit is the maximum number of record to return. Optional, default is 20
fetchPlan is the fetching strategy to use. For more information look at Fetching Strategies. Optional, default is *:1 (1 depth level only)

The command-text can appear in either the URL or the content of the POST transmission. Where the command-text is included in the URL, it must be encoded as per normal URL encoding. By default the result is returned in JSON. To have the result in CSV, pass "Accept: text/csv" in HTTP Request.

Starting from v2.2, the HTTP payload can be a JSON with both command to execute and parameters. Example:

Execute a query passing parameters by name:

{
  "command": "select from V where name = :name and city = :city",
  "parameters": {
    "name": "Luca",
    "city": "Rome"
  }
}

Execute a query passing parameters by position:

{
  "command": "select from V where name = ? and city = ?",
  "parameters": [ "Luca", "Rome" ]
}

Read the SQL section or the Gremlin introduction for the type of commands.

Example

HTTP POST request: http://localhost:2480/command/demo/sql content: update Profile set online = false

HTTP response: 10

Or the same:

HTTP POST request: http://localhost:2480/command/demo/sql/update Profile set online = false

HTTP response: 10

Extract the user list in CSV format using curl

curl --user admin:admin --header "Accept: text/csv" -d "select from ouser" "http://localhost:2480/command/GratefulDeadConcerts/sql"

Batch

POST - Batch

Executes a batch of operations in a single call. This is useful to reduce network latency issuing multiple commands as multiple requests. Batch command supports transactions as well.

Syntax: http://<server>:[<port>]/batch/<database>

Content: { "transaction" : <true|false>, "operations" : [ { "type" : "" }* ] }

Returns: the result of last operation.

Where: type can be:

'c' for create, 'record' field is expected.
'u' for update, 'record' field is expected.
'd' for delete. The '@rid' field only is needed.
'cmd' for commands (Since v1.6). The expected fields are:
'language', between those supported (sql, gremlin, script, etc.)
'command' as the text of the command to execute
'script' for scripts (Since v1.6). The expected fields are:
'language', between the language installed in the JVM. Javascript is the default one, but you can also use SQL (see below)
'script' as the text of the script to execute

Example

{ "transaction" : true,
  "operations" : [
    { "type" : "u",
      "record" : {
        "@rid" : "#14:122",
        "name" : "Luca",
        "vehicle" : "Car"
      }
    }, {
      "type" : "d",
      "record" : {
        "@rid" : "#14:100"
      }
    }, {
      "type" : "c",
      "record" : {
        "@class" : "City",
        "name" : "Venice"
      }
    }, {
      "type" : "cmd",
      "language" : "sql",
      "command" : "create edge Friend from #10:33 to #11:33"
    }, {
      "type" : "script",
      "language" : "javascript",
      "script" : "orient.getGraph().createVertex('class:Account')"
    }
  ]
}

SQL batch

{ "transaction" : true,
  "operations" : [
    {
      "type" : "script",
      "language" : "sql",
      "script" : [ "LET account = CREATE VERTEX Account SET name = 'Luke'",
                   "LET city = SELECT FROM City WHERE name = 'London'",
                   "CREATE EDGE Lives FROM $account TO $city RETRY 100" ]
    }
  ]
}

Function

POST and GET - Function

Executes a server-side function against the database. Returns the result of the function that can be a string or a JSON containing the document(s) returned.

The difference between GET and POST method calls are if the function has been declared as idempotent. In this case can be called also by GET, otherwise only POST is accepted.

Syntax: http://<server>:[<port>]/function/<database>/<name>[/<argument>*]<server>

Where

<name> is the name of the function
<argument>, optional, are the arguments to pass to the function. They are passed by position.

Creation of functions, when not using the Java API, can be done through the Studio in either Orient DB SQL or Java – see the OrientDB Functions page.

Example

HTTP POST request: http://localhost:2480/function/demo/sum/3/5

HTTP response: 8.0

HTTP response: { "size": 61910, "segments": [ {"type": "d", "offset": 0, "size": 33154}, {"type": "h", "offset": 33154, "size": 4859}, {"type": "h", "offset": 3420, "size": 9392}, {"type": "d", "offset": 12812, "size": 49098} ], "dataSize": 47659, "dataSizePercent": 76, "holesSize": 14251, "holesSizePercent": 24 }

Index

NOTE: Every single new database has the default manual index called "dictionary".

GET - Index

Retrieve a record looking into the index.

Syntax: http://<server>:[<port>]/index/<index-name>/<key>

Example

HTTP GET request: http://localhost:2480/dictionary/test HTTP response:

{
  "name" : "Jay",
  "surname" : "Miner"
}

PUT - Index

Create or modify an index entry.

Syntax: http://<server>:[<port>]/index/<index-name>/<key>

Example

HTTP PUT request: http://localhost:2480/dictionary/test content: { "name" : "Jay", "surname" : "Miner" }

HTTP response: No response.

DELETE - Index

Remove an index entry.

Syntax: http://<server>:[<port>]/index/<index-name>/<key>

Example

HTTP DELETE request: http://localhost:2480/dictionary/test HTTP response: No response.

Query

GET - Query

Execute a query against the database. Query means only idempotent commands like SQL SELECT and TRAVERSE. Idempotent means the command is read-only and can't change the database. Remember that in IE6 the URL can be maximum of 2,083 characters. Other browsers supports longer URLs, but if you want to stay compatible with all limit to 2,083 characters.

Syntax: http://<server>:[<port>]/query/<database>/<language>/<query-text>[/<limit>][/<fetchPlan>]

Where:

<language> is the name of the language between those supported. OrientDB distribution comes with "sql" only. Gremlin language cannot be executed with query because it cannot guarantee to be idempotent. To execute Gremlin use command instead.
query-text is the text containing the query to execute
limit is the maximum number of record to return. Optional, default is 20
fetchPlan is the fetching strategy to use. For more information look at Fetching Strategies. Optional, default is *:1 (1 depth level only)

Other key points:

To use commands that change the database (non-idempotent), see the POST – Command section
The command-text included in the URL must be encoded as per a normal URL
See the SQL section for the type of queries that can be sent

Example

HTTP GET request: http://localhost:2480/query/demo/sql/select from Profile

HTTP response:

{ "result": [
{
  "_id": "-3:1",
  "_ver": 0,
  "@class": "Address",
  "type": "Residence",
  "street": "Piazza di Spagna",
  "city": "-4:0"
},
{
  "_id": "-3:2",
  "_ver": 0,
  "@class": "Address",
  "type": "Residence",
  "street": "test",
  "city": "-4:1"
}] }

The same query with the limit to maximum 20 results using the fetch plan *:-1 that means load all recursively:

HTTP GET request: http://localhost:2480/query/demo/sql/select from Profile/20/*:-1

Server

GET - Server

Retrieve information about the connected OrientDB Server. Requires additional authentication to the server.

Syntax: http://<server>:[<port>]/server

Example

HTTP GET request: http://localhost:2480/server HTTP response:

{
  "connections": [{
    "id": "4",
    "id": "4",
    "remoteAddress": "0:0:0:0:0:0:0:1:52504",
    "db": "-",
    "user": "-",
    "protocol": "HTTP-DB",
    "totalRequests": "1",
    "commandInfo": "Server status",
    "commandDetail": "-",
    "lastCommandOn": "2010-05-26 05:08:58",
    "lastCommandInfo": "-",
    "lastCommandDetail": "-",
    "lastExecutionTime": "0",
    "totalWorkingTime": "0",
...

POST - Server

Changes server configuration. Supported configuration are:

any setting contained in OGlobalConfiguation class, by using the prefix configuration in setting-name
logging level, by using the prefix log in setting-name

Syntax: http://<server>:[<port>]/server/<setting-name>/<setting-value>

Example

Example on changing the server log level to FINEST

localhost:2480/server/log.console/FINEST

Example on changing the default timeout for query to 10 seconds

localhost:2480/server/configuration.command.timeout/10000

Connection

POST - Connection

Syntax: http://<server>:[<port>]/connection/<command>/<id>

Where:

command can be:
kill to kill a connection
interrupt to interrupt the operation (if possible)
id, as the connection id. To know all the connections use GET /connection/[<db>]

You've to execute this command authenticated in the OrientDB Server realm (no database realm), so get the root password from config/orientdb-server-config.xml file (last section).
