Worked on reliability improvements for the apache/parquet-java repository, focusing on hardening Parquet I/O around page headers, encryption, and large file footers. Addressed two critical bugs by refining Java-based logic for zero-size data page handling and enhancing decryption processes, ensuring correct identification of empty and encrypted pages. Improved error handling by implementing fail-fast mechanisms for oversized footers, preventing downstream failures and clarifying footer size logging. Expanded test coverage to include edge cases such as empty data pages and encrypted scenarios, increasing release confidence. The work leveraged skills in data compression, file formats, and testing to enhance production safety for large data workloads.
