Release v0.39.0

[XSAM]

Warning

The new introduced OTEL_SEMCONV_STABILITY_OPT_IN environment variable will be supported for at least six months from this release. After this period, support for legacy metrics and Semantic Conventions v1.24.0 may be removed in the next release.

You can start the migration to the new Semantic Conventions v1.30.0 by setting the OTEL_SEMCONV_STABILITY_OPT_IN=database/dup or OTEL_SEMCONV_STABILITY_OPT_IN=database environment variable in your application.

See also the Semantic conventions for database client metrics.

Added

• Support to emit query related attributes for the v1.24.0 and v1.30.0 semantic conventions based on the value of the OTEL_SEMCONV_STABILITY_OPT_IN environment variable. (Migrate db.statement to db.query.text #478)

  • database/dup: Emit both db.statement and db.query.text attributes.
  • database: Emit db.query.text attribute.
  • by default: Emit db.statement attribute.

• New db.client.operation.duration metric following OpenTelemetry semantic conventions. (Migrate db.sql.latency metric to db.client.operation.duration #480)

• Support for configuring metrics behavior based on OTEL_SEMCONV_STABILITY_OPT_IN setting. (Migrate db.sql.latency metric to db.client.operation.duration #480)

  • database/dup: Emit both legacy latency and new duration db.client.operation.duration metrics.
  • database: Emit new duration db.client.operation.duration metric.
  • by default: Emit only the legacy latency metric.
