Logan Riggs enhanced the stability and security of Arrow-based data processing by delivering targeted improvements to the mathworks/arrow and xtdb/arrow-java repositories. He upgraded LLVM to 18.1 to resolve Gandiva JIT compilation issues, synchronized critical methods to ensure thread safety, and fixed edge-case rounding errors in date truncation logic. Logan extended Gandiva’s AES encryption to support multiple key lengths with robust error handling, using C++, Java, and OpenSSL to strengthen cryptographic workflows. His work focused on bug fixing, concurrency, and data structure reliability, resulting in more robust pipelines and improved maintainability for complex vector and date operations.

Feb 1, 2025February 2025: Delivered stability-critical Gandiva improvements across two Arrow repositories. Upgraded LLVM to 18.1 in mathworks/arrow to resolve linking and JIT issues, updated the vcpkg LLVM dependency, and re-enabled previously disabled Java tests, reducing build/test flakiness and restoring test coverage. Implemented a thread-safety fix for Gandiva JIT in xtdb/arrow-java by synchronizing the make and evaluate methods in the Projector, preventing race conditions during LLVM expression creation while preserving existing unit tests and behavior.
