Abhradeep Kundu worked on the apache/phoenix repository, focusing on backend development and database management using Java. During December 2024, he addressed a resource leak issue in query plan cleanup by ensuring internal dependencies were properly cleared when query plans closed, which improved stability and resource utilization for complex workloads. He implemented the fix across multiple query plan implementations and validated the solution with a dedicated integration test that covered scenarios such as table creation, data insertion, and UNION ALL queries. His work demonstrated a methodical approach to integration testing and contributed to reducing out-of-memory risks in heavy-query environments.
