Multi-tracing support for Couchbase 3.2+ #10147

ValentinZakharov · 2025-12-10T09:17:47Z

What Does This Do

Introduced support for combining user-provided Couchbase RequestTracer with Datadog's DataDogRequestTracer, allowing both tracers to operate simultaneously

Added DelegatingRequestTracer that forwards tracing calls to two tracers:

Datadog’s own DatadogRequestTracer the application's custom tracer
DelegatingRequestSpan that mirrors span operations (attributes, events, end(), etc.) to both underlying spans
New instrumentation advice that wraps any user-supplied tracer into this delegating tracer automatically

If the application does not configure a custom tracer, Datadog continues to trace Couchbase operations exactly as before
If the application does configure its own tracer, both tracers now run side-by-side without interfering with each other

Motivation

Сustomer reported that they are using a custom Couchbase RequestTracer in their application
Because Couchbase only allows one tracer to be registered, Datadog’s tracer was being replaced by the custom one. As a result, Couchbase operations were not showing up in the Datadog dashboard at all
