Implement APIGW Inferred Proxy Spans by jordan-wong · Pull Request #8336 · DataDog/dd-trace-java

jordan-wong · 2025-02-04T19:22:13Z

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.

+ InferredProxyContextExtractor() {}
+
+ private Map<String, String> parseInferredProxyHeaders(String input) {
+ Map<String, String> parsedHeaders = new HashMap<>();


What's happening here?
If this always, returns an empty Map - Collections.emptyMap might be better.
It depends on whether or not you need the map to be mutable.

dougqh

I have one question about parseInferredProxyHeaders which appears to always return an empty Map. If that's the case, then returning Collections.emptyMap() would be better.

This reverts commit 5098c6f.
