Implementation of the open feature SDK in the java tracer #9885

manuel-alvarez-alvarez · 2025-10-30T13:36:02Z

What Does This Do

Implements the integration of the OpenFeature SDK within the Java tracer. This includes:

A new module :dd-java-agent:agent-featureflag for feature flag configuration and exposure submission through the EVP proxy.
A new product module :products:openfeature implementing the OpenFeature Java provider
A bridge via :internal-api exposing the FeatureFlagGateway API between tracer internals and the feature flag provider.

Motivation

This adds OpenFeature SDK support to the tracer so feature flag evaluations can be managed and reported consistently through the Datadog feature flagging system.

Additional Notes

Smoke tests are provided as a separate PR

🎯 suggestion: ‏Should we start having dedicated API module for the other products?
Because this is does not feel like "tracing" and I would rather not having sub-modules and third party dependencies from our public tracing API.

So what about starting a :products:open-features for your public API?
Because the direction for 2.x version will be to split all products from tracing and have them own their separate API which can have 3rd party dependency and language version requirement like yours.

Hello @PerfectSlayer, thanks for the input! I did take your suggestion into account and also removed the draft status from the PR, so feel free to continue doing the review. We should also discuss the code owners from the new module (including members of the FFE team)

Not 100% sure, but with latest changes in build scripts we have this as default.
