If this is 90%, 90% of the feed is deletes/removes — consider whether your source DB is doing excessive purging or if channel assignments are churning. + +--- + +### 💡 Output Error Rate (%) + +```promql +rate(changes_worker_output_errors_total[5m]) + / rate(changes_worker_output_requests_total[5m]) * 100 +``` + +**Insight:** Should be **0%** in a healthy system. Even 1% means your downstream endpoint is rejecting docs. Compare `output_errors_by_method_total{method="PUT"}` vs `{method="DELETE"}` to see if writes or deletes are failing — e.g. if DELETE errors are high but PUT errors are zero, your endpoint may not support DELETE operations. + +--- + +### 💡 Average Document Size (Ingest) + +```promql +rate(changes_worker_bytes_received_total[5m]) + / rate(changes_worker_changes_received_total[5m]) +``` + +**Insight:** Average bytes per incoming change. Tells you if your docs are 500 bytes or 50 KB. Critical for capacity planning — multiply by your expected changes/sec to predict bandwidth needs. + +--- + +### 💡 Average Payload Size (Output) + +```promql +rate(changes_worker_bytes_output_total[5m]) + / rate(changes_worker_output_requests_total[5m]) +``` + +**Insight:** Compare against the ingest doc size above. If you switched `output_format` from JSON to msgpack, this should shrink. If you switched to XML, it should grow. A ratio of `bytes_output / bytes_received` ≈ 1.0 means JSON→JSON with minimal transformation. + +--- + +### 💡 Input-to-Output Byte Ratio + +```promql +rate(changes_worker_bytes_output_total[5m]) + / rate(changes_worker_bytes_received_total[5m]) +``` + +**Insight:** Values < 1.0 mean compression (msgpack, filtering out fields). Values > 1.0 mean expansion (XML, adding envelope metadata). A sudden change means your transformation pipeline or serialization format changed. + +--- + +### 💡 Staleness — Seconds Since Last Successful Poll + +```promql +time() - changes_worker_last_poll_timestamp_seconds +``` + +**Insight:** How stale your data is. If this exceeds 2–3× your `poll_interval_seconds`, the worker is stuck or the gateway is unreachable. Alert on `> 120` for a 30s poll interval. + +--- + +### 💡 Average Batch Size Over Time + +```promql +rate(changes_worker_changes_received_total[5m]) + / rate(changes_worker_poll_cycles_total[5m]) +``` + +**Insight:** How many changes arrive per poll. Full batches (= your `throttle_feed` limit) mean there's a backlog. Empty batches (≈ 0) mean the worker is caught up. Trending upward → write load is increasing on the source. + +--- + +### 💡 Average Time Per Poll Cycle + +```promql +changes_worker_uptime_seconds + / changes_worker_poll_cycles_total +``` + +**Insight:** Rough average loop cadence. Should be close to your `poll_interval_seconds` when idle. If it's much higher, processing time or output latency is dominating. + +--- + +### 💡 Feed Delete Rate (%) + +```promql +rate(changes_worker_feed_deletes_seen_total[5m]) + / rate(changes_worker_changes_received_total[5m]) * 100 +``` + +**Insight:** True deletion activity in the source DB, regardless of your `ignore_delete` setting. If this is high and `deletes_forwarded_total` is zero, your filter is working. If both are high, your downstream is processing a lot of tombstones — you may want to batch or throttle. + +--- + +### 💡 PUT vs DELETE Split (%) + +```promql +rate(changes_worker_output_requests_by_method_total{method="DELETE"}[5m]) + / rate(changes_worker_output_requests_total[5m]) * 100 +``` + +**Insight:** What % of your output traffic is deletions. A value of 50% means half your downstream writes are deletes — that's unusual and worth investigating (TTL expiration? mass purge?). + +--- + +### 💡 Docs Fetched Per Processed Change + +```promql +rate(changes_worker_docs_fetched_total[5m]) + / rate(changes_worker_changes_processed_total[5m]) +``` + +**Insight:** Only relevant when `include_docs=false`. Should be ≈ 1.0. If higher, docs are being fetched redundantly (e.g. a `_bulk_get` retry fetched some docs again). + +--- + +### 💡 Poll Error Rate (%) + +```promql +rate(changes_worker_poll_errors_total[5m]) + / rate(changes_worker_poll_cycles_total[5m]) * 100 +``` + +**Insight:** Gateway reliability. If this is > 0 consistently, the gateway is flaky. Cross-reference with `retries_total` — if retries are high but poll errors are zero, the retries are succeeding (the gateway recovers). If both are high, the gateway is in trouble. + +--- + +### 💡 Retry Success Rate + +```promql +1 - ( + rate(changes_worker_retry_exhausted_total[5m]) + / rate(changes_worker_retries_total[5m]) +) +``` + +**Insight:** What % of retries eventually succeed. A value of 1.0 (100%) means every transient error recovered. If `retry_exhausted_total` is climbing, your `max_retries` may be too low or the target is truly down. + +--- + +### 💡 DLQ Growth Rate + +```promql +rate(changes_worker_dead_letter_total[5m]) +``` + +**Insight:** How fast the dead-letter queue is growing. Any sustained rate > 0 means docs are failing to process. Combine with `dlq_pending_count` to see the current backlog, and `dlq_last_write_epoch` to see how recently it grew. + +--- + +### 💡 Attachment Download Success Rate (%) + +```promql +rate(changes_worker_attachments_downloaded_total[5m]) + / (rate(changes_worker_attachments_downloaded_total[5m]) + + rate(changes_worker_attachments_download_errors_total[5m])) * 100 +``` + +**Insight:** How reliable attachment downloads are. If below 100%, check `attachments_missing_total` (404s — the attachment was deleted) vs `attachments_download_errors_total` (network/timeout errors). + +--- + +### 💡 Attachment Pipeline Efficiency + +```promql +rate(changes_worker_attachments_uploaded_total[5m]) + / rate(changes_worker_attachments_detected_total[5m]) +``` + +**Insight:** What fraction of detected attachments make it through download → upload. Values < 1.0 mean attachments are being lost to filters, errors, or stale revisions. Check `attachments_skipped_total`, `attachments_stale_total`, and `attachments_orphaned_uploads_total` to find where. + +--- + +### 💡 DB Transient vs Permanent Error Ratio + +```promql +rate(changes_worker_db_transient_errors_total[5m]) + / (rate(changes_worker_db_transient_errors_total[5m]) + + rate(changes_worker_db_permanent_errors_total[5m])) +``` + +**Insight:** If most errors are transient (deadlocks, connection drops), the system will self-heal via retries. If most are permanent (constraint violations, type mismatches), your schema mappings need fixing. + +--- + +### 💡 Inbound vs Outbound Auth Failure Rate + +```promql +# Inbound (gateway) auth failure rate +rate(changes_worker_inbound_auth_failure_total[5m]) + / rate(changes_worker_inbound_auth_total[5m]) * 100 + +# Outbound (output) auth failure rate +rate(changes_worker_outbound_auth_failure_total[5m]) + / rate(changes_worker_outbound_auth_total[5m]) * 100 +``` + +**Insight:** Pinpoints which side has auth issues. If inbound auth failures are climbing, your gateway credentials (basic/session/bearer) are expiring. If outbound auth failures are climbing, your output endpoint's credentials need refreshing. + +--- + +### 💡 Backpressure Impact — Wasted Time + +```promql +changes_worker_backpressure_delay_seconds_total + / changes_worker_uptime_seconds * 100 +``` + +**Insight:** What % of the worker's lifetime has been spent throttled by backpressure. If this exceeds 10%, your output endpoint is too slow and is bottlenecking the entire pipeline. + +--- + +### 💡 Process Memory Growth (Leak Detection) + +```promql +deriv(changes_worker_process_memory_rss_bytes[1h]) +``` + +**Insight:** If RSS memory is growing linearly over hours, you likely have a memory leak. Combine with `python_gc_gen2_count` — if gen2 objects are growing too, objects are surviving garbage collection. + +--- + +## Source Files + +| File | Role | +|------|------| +| `main.py` → `MetricsCollector` class | All global metrics: counters, gauges, summaries, system/process metrics | +| `main.py` → `_metrics_handler()` | HTTP handler for `GET /_metrics` | +| `db/db_base.py` → `DbMetrics` class | Per-engine/per-job RDBMS metric proxy + `render_all()` | +| `cloud/cloud_base.py` → `CloudMetrics` class | Per-provider/per-job cloud metric proxy + `render_all()` | +| `rest/changes_http.py` → `RetryableHTTP` | Increments `retries_total`, `retry_exhausted_total`, auth metrics | +| `rest/attachment_postprocess.py` | Increments attachment conflict/stale/orphaned/skipped metrics | diff --git a/docs/MULTI_PIPELINE_PLAN.md b/docs/MULTI_PIPELINE_PLAN.md index b530fc6..428f3f7 100644 --- a/docs/MULTI_PIPELINE_PLAN.md +++ b/docs/MULTI_PIPELINE_PLAN.md @@ -16,7 +16,7 @@ This document outlines the design for supporting **multiple concurrent pipelines ┌──────────────┐ ┌───────────┐ ┌──────────────┐ │ 1 SOURCE │──────►│ 1 PROCESS │──────►│ 1 OUTPUT │ │ _changes │ │ filter, │ │ HTTP / DB / │ -│ feed │ │ fetch, │ │ stdout │ +│ feed │ │ fetch, │ │ Cloud │ │ │ │ transform│ │ │ └──────────────┘ └───────────┘ └──────────────┘ ``` @@ -36,7 +36,7 @@ Support **N independent pipelines** running concurrently via Python threads, whe Thread 1: SG/db.us.prices/_changes ──► filter/transform ──► PostgreSQL (prices table) Thread 2: SG/db.us.orders/_changes ──► filter/transform ──► PostgreSQL (orders table) Thread 3: SG/db.eu.prices/_changes ──► filter/transform ──► REST API endpoint -Thread 4: Edge/inventory/_changes ──► filter/transform ──► stdout +Thread 4: Edge/inventory/_changes ──► filter/transform ──► Cloud Storage ``` Each thread runs its own asyncio event loop and is fully isolated — its own HTTP session, checkpoint, metrics, and output connection. @@ -133,7 +133,7 @@ main() │ ├── Thread-3: Pipeline("eu-prices-to-pg") │ │ └── asyncio.run(poll_changes(pipeline_cfg_3)) │ │ - │ └── Thread-4: Pipeline("inventory-to-stdout") + │ └── Thread-4: Pipeline("inventory-to-cloud") │ └── asyncio.run(poll_changes(pipeline_cfg_4)) │ ├── wait for shutdown signal diff --git a/docs/RDBMS_IMPLEMENTATION.md b/docs/RDBMS_IMPLEMENTATION.md index beed57f..a40ba77 100644 --- a/docs/RDBMS_IMPLEMENTATION.md +++ b/docs/RDBMS_IMPLEMENTATION.md @@ -407,7 +407,7 @@ The `PostgresOutputForwarder` reads connection fields from the resolved engine c | `sync_commit` | `false` | **Advanced.** When `false` (default), sets `synchronous_commit = OFF` on each connection — Postgres does not wait for WAL flush after commit. **2-5x throughput improvement** for high-volume writes.

    📊 Docs Fetched Per Processed Change

    / rate(changes_worker_changes_processed_total[5m]) +
    +

    🧠 PRO TIP — Retry Success Rate

    +

    What % of retries eventually succeed. A value of 1.0 (100%) means every transient error recovered. If retry_exhausted_total is climbing, your max_retries is too low or the target is truly down.

    +

+)
    +
    + +
    +

    🧠 PRO TIP — DLQ Growth Rate

    +

    How fast the dead-letter queue is growing. Any sustained rate > 0 means docs are failing. Combine with dlq_pending_count to see the current backlog.

    + 
    rate(changes_worker_dead_letter_total[5m])

    🧠 PRO TIP — Attachment Download Success Rate (%)

    +

    How reliable attachment downloads are. If below 100%, check attachments_missing_total (404s) vs attachments_download_errors_total (network errors) to pinpoint the cause.

    + 
    rate(changes_worker_attachments_downloaded_total[5m])

+     + rate(changes_worker_attachments_download_errors_total[5m])) * 100
    +
    + +
    +

    🧠 PRO TIP — Attachment Pipeline Efficiency

    +

    What fraction of detected attachments make it through download → upload. Values < 1.0 mean attachments are being lost to filters, errors, or stale revisions. Check attachments_skipped_total, attachments_stale_total, and attachments_orphaned_uploads_total.

    + 
    rate(changes_worker_attachments_uploaded_total[5m])
+  / rate(changes_worker_attachments_detected_total[5m])
    +
    + +
    +

    🧠 PRO TIP — DB Transient vs Permanent Error Ratio

    +

    If most DB errors are transient (deadlocks, connection drops), the system self-heals via retries. If most are permanent (constraint violations, type mismatches), your schema mappings need fixing.

    + 
    rate(changes_worker_db_transient_errors_total[5m])

+     + rate(changes_worker_db_permanent_errors_total[5m]))
    +
    + +

    🧠 PRO TIP — Backpressure Impact (%)

    +

    What % of the worker's lifetime has been spent throttled. If > 10%, your output endpoint is the bottleneck.

    + Skipped Skipped Documents +

    +

    A document is skipped when the pipeline receives it from the change feed but determines there is nothing to send to the output. Skipped documents do not reach the output — they are silently dropped. This is different from errors: skipped documents are not failures, and the checkpoint still advances past them. The output_skipped_total metric tracks how many documents were skipped.

    + +

    Skipped vs Filtered vs Errors

    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    OutcomeWhereReaches Output?Description
    FilteredChanges feed❌ NoRemoved at the source — deletes and removes are stripped before processing begins.
    SkippedWorker / Mapper❌ NoMade it to the worker but was dropped — no mapper match, null doc, empty mapping result, or ignored delete.
    DeletesWorker → Output✅ Yes (DELETE)Tombstone (deleted=true) from the source. Forwarded to the output as a DELETE operation — removes the corresponding rows/objects from the target. See Deletes.
    Error → DLQOutput✅ AttemptedReached the output, delivery was attempted, but it failed. Sent to the Dead Letter Queue for retry.
    SuccessOutput✅ YesDelivered successfully to the target endpoint or database.
    +
    + +

    When Does a Skip Happen?

    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    ConditionDescriptionLog Message
    Null DocumentThe change feed entry has no document body. This can happen with tombstoned or purged documents where the body is unavailable.OUTPUT: received None doc – skipped
    No Mapper MatchThe document does not match any configured JSONPath filter in the schema mapping. If your mapping uses a filter expression (e.g. $.type == "order"), documents that don't satisfy it are skipped.MAPPING: doc does not match any mapping filter – skipped
    Empty OperationsThe mapper matched the document, but transforms or field filters resulted in zero database operations. For example, all mapped fields were null or excluded by a condition.MAPPING: mapper matched but produced no operations – skipped
    Delete IgnoredCloud / HTTP output mode with on_delete: "ignore". Delete events are intentionally discarded instead of being forwarded.OUTPUT: delete ignored (on_delete=ignore) – skipped
    No Mapping LoadedNo schema mapping files were found or all mapping definitions are inactive. Every document is skipped until a valid mapping is configured.MAPPING: no schema mapping loaded – skipping doc
    Data Error (skip mode)A data error occurred and data_error_action is set to skip. The document is dropped instead of going to the DLQ.OUTPUT: data error – skipped doc (data_error_action=skip)
    +
    + +

    Most Common Causes

    +

    In practice, the vast majority of skips are No Mapper Match and Empty Operations. This simply means the document doesn't match your mapping configuration, so there is nothing to write to the output. This is normal when your mapping targets a subset of document types (e.g. only type: "order") and the change feed also contains other types.

    + +

    Debugging Skipped Documents

    +
    + Tip: All skip events are now logged at INFO level with the doc_id and reason. Go to the Logs page and search for "skipped" to see every skipped document. You can filter by the MAPPING or OUTPUT log keys to narrow results. +
    +
    + Note: Skipped documents also appear in the Document Fate chart on the Dashboard when you click the changes_worker node. If the skipped count is unexpectedly high, check that your schema mapping filters and transform names are correct. +
    +
    +
    + + +
    +
    +

    + Deletes Deletes & Tombstones +

    +

    The _changes feed can signal that a document should be removed from the consumer's perspective in two ways:

    +
    + + + + + + + + + + + + + + +
    FlagMeaningDocument still exists?
    "deleted": trueThe document was permanently deleted at the source. The change entry is a tombstone — a minimal record with just _id, _rev, and _deleted.❌ No — the document is gone.
    "removed": trueThe document still exists at the source, but you (the feed consumer) no longer have access to it — typically because it was removed from your channel, or your access was revoked. From the consumer's perspective this is equivalent to a delete.✅ Yes — but not for you.
    +
    +

    Both flags are treated identically by the pipeline: the document is forwarded to the output as a DELETE operation (unless filtered). The dashboard's Deletes counter tracks the combined total of both deleted and removed entries that were forwarded.

    + +

    What Happens to a Delete / Remove?

    +
    + + + + + + + + + + + + + + +
    OutcomeWhenWhat Happens
    Filteredignore_delete: true or ignore_remove: trueThe entry is silently dropped before it reaches the output. Counted in changes_deleted_total or changes_removed_total (filtered).
    Forwarded → DELETEignore_delete: false and ignore_remove: false (defaults)The entry is sent to the output as a DELETE operation. For RDBMS: rows are deleted from all mapped tables. For HTTP: a DELETE request is sent. For Cloud: the object is deleted (or tombstoned, per on_delete setting). Counted in deletes_forwarded_total.
    +
    + +

    RDBMS Delete Handling

    +

    When a tombstone reaches an RDBMS output, the mapper generates DELETE SQL statements. Each table in the mapping has an on_delete setting:

    +
    + + + + + + + + + + + + +
    on_deleteBehavior
    "delete"Generate DELETE FROM table WHERE doc_id = $1. For multi-table mappings, child tables are deleted first (FK safety), then the parent, all inside a transaction.
    "ignore"Skip this table — the row is left in place even though the source document was deleted.
    +
    + +

    Related Metrics

    +
    + + + + + + + + + +
    MetricTypeDescription
    changes_worker_feed_deletes_seen_totalcounterTotal entries with deleted=true seen in the raw feed — always counted regardless of filter settings.
    changes_worker_feed_removes_seen_totalcounterTotal entries with removed=true seen in the raw feed — always counted regardless of filter settings.
    changes_worker_deletes_forwarded_totalcounterDeletes + removes that passed filtering and were forwarded to the output as DELETE operations.
    changes_worker_changes_deleted_totalcounterDeletes filtered out (skipped) because ignore_delete: true.
    changes_worker_changes_removed_totalcounterRemoves filtered out (skipped) because ignore_remove: true.
    +
    + +
    + Tip: The relationship is: deletes_forwarded = (feed_deletes_seen − changes_deleted) + (feed_removes_seen − changes_removed). With both ignore_delete and ignore_remove set to false (the defaults), deletes_forwarded equals feed_deletes_seen + feed_removes_seen. +

    +

    + Pending Pending Documents +

    +

    Pending is a calculated value — not a queue or a buffer — that represents the number of documents the pipeline has received but has not yet accounted for. It tells you whether the system is keeping up with the incoming change feed.

    + +

    How Is Pending Calculated?

    +
    + + + + + + + + +
    FormulaDescription
    Pending = Received
    − Success
    − Errors − DLQ
    − Skipped    		 +

    Received = total docs from the changes feed (changes_received_total).

    +

    Success = docs successfully written to output (output_success_total).

    +

    Errors + DLQ = docs that failed delivery (output_errors_total + dead_letter_total).

    +

    Skipped = docs that did not reach output (output_skipped_total). See Skipped Documents.

    +

    Note: Filtered docs (deletes/removes) are stripped before changes_received_total is incremented, so they do not affect the Pending count.

    +
    +
    + +

    How to Read the Pending Number

    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    Pending BehaviourWhat It MeansAction
    Flat at 0Every received document has been accounted for (success + error + skip). The pipeline is healthy and keeping up.None — this is the ideal state.
    Rising steadilyInput is outpacing output. Documents are being received faster than they can be processed and delivered.Check output latency, batch size, and target endpoint performance.
    Rising + high Fail %Errors are causing the backlog. Failed documents that aren't being resolved are accumulating.Check the DLQ, output endpoint health, and error logs.
    DroppingThe system is catching up — output rate exceeds input rate. The backlog is draining.None — the system is recovering.
    Stuck at a fixed number > 0A batch of documents was received but never processed. This can happen if the worker restarted mid-batch or if some documents are stuck in processing.Check worker logs for errors. Restart the worker if needed — the checkpoint will resume from the last saved position.

    Pending and Checkpoints — What Happens If Something Goes Wrong?

    +

    Pending documents are documents the worker has received but not yet checkpointed. The checkpoint only advances after a batch is fully processed. This means pending documents are "at risk" — if the worker crashes or the output goes down, those documents have not been saved as complete.

    +
    + + + + + + + + + + + + + + + + +
    ModeWhat Happens to Pending Docs
    Sequential
    sequential: true    		 +

    Documents are processed one at a time, in order. The checkpoint advances after each every_n_docs sub-batch.

    +

    On failure: The checkpoint has not advanced past the current batch. On restart, the worker resumes from the last saved checkpoint and re-processes all pending documents. No data is lost.

    +
    Non-Sequential (parallel)
    sequential: false    		 +

    Documents are dispatched as concurrent tasks. The checkpoint advances only after all docs in the batch complete.

    +

    On failure: Failed individual docs go to the DLQ (if halt_on_failure: false). If the output goes completely down or the worker shuts down, pending docs that were in-flight are DLQ'd (when dlq_inflight_on_shutdown: true) and the checkpoint is not advanced.

    +
    Output Down +

    If the output endpoint becomes unreachable mid-batch, the worker stops processing and does not advance the checkpoint. The log message reads: OUTPUT DOWN – not advancing checkpoint past since=…

    +

    On the next poll cycle (or restart), the worker retries from the last good checkpoint, re-processing all pending documents.

    +
    +
    +
    + Key point: Pending documents are safe. The checkpoint guarantees at-least-once delivery — if anything goes wrong, the worker will re-process from where it left off. Documents are never silently lost; they either succeed, go to the DLQ, or are retried on restart. +
    + +
    + Tip: Pending is not a metric exported to Prometheus — it is derived in the UI from other counters. If you need to alert on backlog size in an external monitoring system, compute it as: changes_received_total − output_success_total − output_errors_total − dead_letter_total − output_skipped_total. +
    +
    + Note: Pending can never go below zero. If the subtraction yields a negative number (e.g. due to counter resets after a restart), the UI clamps it to 0. +
    +
    +
    +

    DLQ Dead Letter Queue

    -

    When halt_on_failure: false, failed documents are written to the dead letter queue with full context for later replay.

    +

    When halt_on_failure: false, failed documents are written to the dead letter queue with full context for later replay. The dead_letter_total metric tracks how many documents have been written to the DLQ.

    + +

    When Does a Document Go to the DLQ?

    +

    A document is written to the DLQ when the output returns ok: false and halt_on_failure is false. The key requirement is: the output tried to deliver the document and failed. This is different from a skip, where the document never reaches the output.

    TriggerDescriptionLog Message / DLQ Reason
    Client Error (4xx)The HTTP output endpoint returned a 4xx status (e.g. 400 Bad Request, 404 Not Found, 409 Conflict, 422 Unprocessable). The document payload is rejected by the endpoint.OUTPUT: client error (4xx)
    Reason: client_error:<status>
    Server Error (5xx)The HTTP endpoint returned a 5xx status (e.g. 500, 502, 503) after all retries were exhausted. The server could not process the request.OUTPUT: server error (5xx) after retries
    Reason: server_error:<status>
    Redirect Error (3xx)The HTTP endpoint returned a redirect (3xx). PouchPipes does not follow redirects — this is treated as a delivery failure.OUTPUT: redirect error (3xx)
    Reason: redirect:<status>
    Connection FailureThe output endpoint could not be reached — DNS failure, connection refused, or network unreachable. All retries exhausted.OUTPUT: connection failed (DNS / refused / unreachable)
    Reason: connection_failure
    Request TimeoutThe HTTP request to the output endpoint timed out after the configured request_timeout seconds.OUTPUT: request timed out
    Reason: connection_failure
    RDBMS Permanent ErrorA non-transient database error occurred — e.g. constraint violation, data type mismatch, invalid SQL. The error is not retryable.OUTPUT: permanent error
    Reason: data_error:<class>
    Mapping ErrorThe schema mapper threw an exception while processing the document (e.g. JSONPath evaluation failure, transform error).MAPPING: mapping error
    Reason: data_error:mapping
    Shutdown In-FlightThe worker received a shutdown signal while documents were still being processed. If dlq_inflight_on_shutdown: true, remaining unprocessed docs in the batch are written to the DLQ.SHUTDOWN: DLQ'd N remaining docs from sub-batch
    Reason: shutdown_inflight

    DLQ vs Skip vs Halt

    + + + + + + + + + + + + + + + + + + + +
    OutcomeWhenCheckpoint
    DLQhalt_on_failure: false and the output fails (any trigger above)Advances
    Halthalt_on_failure: true (default) and the output failsDoes NOT advance
    SkipDocument never reaches output (no mapper match, null doc, etc.)Advances
    +
    + +
    + data_error_action: For 4xx client errors (HTTP) and permanent RDBMS errors, the data_error_action config controls behavior. Set to "dlq" (default) to write to the DLQ. Set to "skip" to silently discard the doc without a DLQ entry. +
