Worked on the Altinity/ClickHouse repository to enhance test coverage and reliability for analytics workloads. Developed and integrated a comprehensive suite of tests for array functions using Python and SQL, focusing on correctness and type safety for utilities such as arrayMap, arrayFilter, and arraySum. Improved error handling by tightening type checks within arrayFilter, supporting regression safety and robust database testing. Additionally, addressed intermittent failures in the CI suite by implementing a retry mechanism for MinIO object deletion, ensuring reliable cleanup before disk configuration tests. This work strengthened integration testing processes and contributed to more stable and predictable continuous integration outcomes.
