Over a two-month period, contributed to the infiniflow/infinity repository by building and refining a robust snapshot management system for the Infinity database. Developed end-to-end snapshot lifecycle features—creation, restoration, listing, and deletion—integrated with abstract database interfaces and a remote thrift client to enhance data resilience and recovery. Addressed critical persistence gating and transaction update conflict bugs, improving data integrity and concurrency control. Enhanced reliability through error handling improvements and retry logic for checkpointing. Introduced CI/CD workflows using GitHub Actions and clang-format to enforce consistent C++ code style. Work leveraged C++, Python, and Thrift, emphasizing testing and maintainability throughout.
