Remove deprecated startSpan and use integration name for telemetry by amarziali · Pull Request #11181 · DataDog/dd-trace-java

amarziali · 2026-04-22T13:30:21Z

What Does This Do

Removes the 4 deprecated startSpan overloads from AgentTracer that accepted a CharSequence span name as the only/first argument and defaulted to "datadog" as the instrumentation name:

// removed:
startSpan(CharSequence spanName)
startSpan(CharSequence spanName, long startTimeMicros)
startSpan(CharSequence spanName, AgentSpanContext parent)
startSpan(CharSequence spanName, AgentSpanContext parent, long startTimeMicros)

All ~145 call sites across ~143 instrumentation files have been migrated to the non-deprecated form that explicitly passes the integration's own name as the first String argument (matching instrumentationNames()[0] from the nearest decorator). This ensures spans are attributed to the correct integration rather than the generic "datadog" default.

The private DEFAULT_INSTRUMENTATION_NAME = "datadog" constant in AgentTracer is also removed; the two remaining deprecated methods in TracerAPI (buildSpan(CharSequence) and singleSpanBuilder(CharSequence)) now inline the "datadog" literal directly.

No behaviour change — this is a pure refactor. The instrumentation name passed to the tracer now matches what each integration already declared as its own name.
