Correlation

Request Correlation

Optional request-level identity links logs and traces when you emit the same value on both sides. It does not replace trace_id.

Identifiers

request_id — customer / product field on logs and traces.
correlation_id — same request-level identity in stores that use this name (for example ClickHouse span rows).

Emit via log context requestId or OTEL attribute http.request_id (promoted on ingest).

DIRECT joins require equal stored request / correlation identity. Log search: request: / requestid:.

GET /api/app/correlation?type=request&id=…

Limitations

Platform middleware x-request-id is not automatically a product correlation namespace.
trace_id remains authoritative for distributed joins — do not substitute request id for it.
Never invent request links from timestamps.
