Implement APIGW Inferred Proxy Spans by zarirhamza · Pull Request #9154 · DataDog/dd-trace-java

zarirhamza · 2025-07-11T02:05:28Z

What Does This Do

Adds an inferred proxy span as the parent of http request spans if http headers with x-dd-proxy are detected

Motivation

We want to have observability of router/ proxy services like AWS API Gateway, that redirect client calls to various targets. There is distinct http header metadata available to us from http requests that can allow us to "infer" the presence of these proxy services.

Additional Notes

Confirm implementation
Add tests
Check telemetry
Update system tests
