Developed a critical feature for the open-telemetry/opentelemetry-collector-contrib repository, enabling the Datadog Receiver to handle the /api/v0.2/stats endpoint for APM trace stats ingestion. Leveraging Go and backend development expertise, implemented a handler that decodes gzipped MsgPack payloads from the Datadog Agent, translates them into StatsPayload objects, and converts these into OpenTelemetry-compatible metrics for downstream OTLP backends. This work restored the end-to-end telemetry flow between the Datadog Agent and OTLP backends, improving data fidelity and reliability. The implementation included inline code comments for maintainability and was prepared for future documentation, with contributions made collaboratively.
