feat: add dbm dynamic_service mode by raphaelgavache · Pull Request #18269 · DataDog/dd-trace-py

raphaelgavache · 2026-05-26T15:56:17Z

Introduces a new DD_DBM_PROPAGATION_MODE=dynamic_service value that combines service mode behaviour with automatic SQL base hash injection, without requiring users to separately set DD_DBM_INJECT_SQL_BASEHASH=true.

(similar implem in dd-trace-java)

Setting dynamic_service is equivalent to:

DD_DBM_PROPAGATION_MODE=service
DD_DBM_INJECT_SQL_BASEHASH=true
Like service mode, dynamic_service injects service metadata tags (ddps, dddbs, ddh, dddb, dde, ddpv) and the base hash tag (ddsh) into comments. It does not inject traceparent (that remains exclusive to full mode).

Tested against this system-test
with

env TEST_LIBRARY=python ./run.sh DBM_DYNAMIC_SERVICE -F tests/integrations/test_dbm.py::Test_Dbm_DynamicService_Postgres tests/integrations/test_dbm.py::Test_Dbm_DynamicService_Postgres::test_dbm_dynamic_service
