Jose Luis Lobell developed a Go-based MySQL registry store for the opendatahub-io/feast repository, enabling the Go feature server to read registry data directly from MySQL and matching the capabilities of the Python SDK’s SQL registry store. He implemented configurable connection pooling and ensured robust database management by supporting MySQL URL parsing, registry table loading, and protobuf unmarshaling. His work included comprehensive unit testing, using both in-memory SQLite and MySQL scheme routing to validate registry loading. By aligning the Go SDK’s registry behavior with Python’s SQLAlchemy schema, he established a solid foundation for production-grade, cross-SDK registry integration.
