Worked on the TDengine repository to enhance memory management and test coverage in the database storage path. Introduced a buffer pool allocation guard in metaMalloc, ensuring that memory requests exceeding available buffer pool space are safely handled, and updated cache flush logic in tdbPCacheFetchImpl to maintain data integrity on allocation failure. Refactored and expanded restore-after-abort tests in tdbPageFlushTest.cpp, improving reliability and coverage for recovery scenarios following interrupted page flushes. Leveraged C and C++ to implement robust memory management, database internals, and test automation practices, reducing production risk and strengthening the reliability of core database operations.

Mar 1, 2025March 2025 focused on hardening memory management in TDengine and expanding restore test coverage to improve reliability and data integrity. Delivered a guard in memory allocation that prevents buffer pool over-allocation and ensured cache flush on allocation failure, and expanded tests to cover abort scenarios in page flush restore. These changes reduce production risk, improve recovery behavior, and demonstrate strong C/C++ memory management and test automation skills.
