PROFILE
Avinaash Gupta
Avinaash contributed to the facebookincubator/velox repository by developing and optimizing batch serialization for remote function calls using C++. He implemented a batch serializer and a specialized rowVectorToIOBufBatch to reduce payload size, focusing on preserving encoding semantics for efficient data transfer. His work involved integrating these features into both client and server paths, ensuring backward compatibility and addressing stability concerns by rolling back changes when crashes and test failures occurred. Through careful debugging and performance optimization, Avinaash achieved over 70% payload reduction in tests, particularly benefiting UDF-based remote calls with constant parameters, demonstrating depth in system programming and remote function handling.

Dec 1, 2025Monthly work summary for 2025-12 (facebookincubator/velox). Focused on batch serialization experiments for remote functions, including preserve-encoding payload optimization and batch-based serialization path. Implemented new batch serializer and a specialized rowVectorToIOBufBatch, with client/server integration and backward-compatibility. However, the work was rolled back due to crashes and test instability, reverting to a simpler payload serialization. This ensured stability and compatibility while preserving learning for future rollout.
