Developed the Datadog Stateful Logs feature for the DataDog/lading repository, introducing bidirectional gRPC log streaming through a newly designed protocol. This work involved defining Protocol Buffers messages and implementing a gRPC service in Rust to enable real-time, stateful log ingestion and replication within the DataDog agent. By wiring the new streaming path into the agent, the solution improved both the reliability and scalability of log processing. The project focused on feature delivery and stabilization, with no major bugs reported during the period. Demonstrated strong proficiency in Rust, Protocol Buffers, and gRPC while enhancing the agent’s logging capabilities.
