Worked on the open-telemetry/otel-arrow repository to deliver a context-preserving OTAP Exporter, focusing on reliable data pipeline acknowledgments. Leveraged Rust and Tokio asynchronous programming to implement bidirectional gRPC streaming and channel-based data flows, ensuring that context was preserved and propagated with each data batch. Replaced unreliable sleep-based test synchronization with event-driven waits, which improved test determinism and reliability across environments. The approach enabled deterministic handling of ACK and NACK messages, reducing data loss and enhancing pipeline responsiveness. This work emphasized backend development and robust testing practices, resulting in a more reliable and maintainable telemetry export pipeline for the project.
