Closing the Observability Gap: Connecting Application Traces to Database Execution Plans 

This article explores how linking distributed application traces to database execution plans helps engineers bridge the observability gap during performance investigations. By injecting trace context into SQL queries, teams can pivot from identifying slow application spans to analyzing specific database-side behaviors, such as plan regressions. This integrated approach enables a transition from detecting vague latency symptoms to providing data-driven evidence of a root cause.
