Worked on the facebookincubator/velox repository to deliver a suite of typed IP address utility functions, focusing on improving both correctness and performance in backend data pipelines. Developed in C++ with thorough testing, the new features enable direct operations on IPADDRESS and IPPREFIX types, eliminating the need for error-prone string parsing and reducing the risk of IPv4 and IPv6 misclassification. By introducing functions such as ip_version and ip_prefix_masklen, the work streamlined IP introspection and reduced dataflow latency. This approach aligned Velox’s IP capabilities with modern backend standards, supporting more reliable and maintainable IP-based query processing in production environments.
