Worked on the confluentinc/kafka-rest repository to migrate internal ConsumerGroup state handling to Kafka’s GroupState, updating mappings and simplifying conversion logic to improve reliability and reduce log noise. Addressed unit test failures resulting from this migration to maintain continuous integration stability, and enhanced AdminClient compatibility by refining GroupIdNotFoundException handling and aligning state mappings. Cleaned up integration test infrastructure by removing ZooKeeper as a testable quorum type, reflecting modern Kafka deployment practices and reducing test fragility. Utilized Java and Kafka for backend and API development, with a focus on code cleanup, error handling, and integration testing to support production-like environments.
December 2024: Delivered key consumer-group state work and targeted test infra cleanup for confluentinc/kafka-rest. Migrated internal ConsumerGroup state handling to Kafka GroupState, updated mappings, simplified conversion logic, and removed noisy debug prints to improve reliability and reduce log noise. Fixed unit test failures following the GroupState migration to maintain CI stability. Implemented AdminClient compatibility improvements (GroupIdNotFoundException handling and mapping alignment) and cleaned up test infra by removing ZooKeeper as a testable quorum type to reflect current Kafka deployments. These changes enhance stability in production-like environments and align with modern Kafka deployments.
