Month: 2025-10 Key features delivered: - Return clause enhancement: include generated and synthetic sub-columns in RETURNING results; added utilities and merge logic for synthetic children in the Indexer; tests validate synthetic/nested sub-columns and null handling. Major bugs fixed: - Optimizer safety: apply equi-join-to-lookup-join rule only to simple equi-joins to prevent misapplication on complex queries; avoids SQLParseException and improves optimization accuracy. - Object-column generated sub-columns validation and documentation: implements checks to disallow generated sub-columns within object arrays or referencing their subcolumns; updates tests and documentation to reflect supported structures and clarify object column behavior. Overall impact and accomplishments: - Improved correctness and reliability of queries involving generated sub-columns; reduced optimizer risk; enhanced test coverage and documentation; better alignment with performance goals and user expectations. Technologies/skills demonstrated: - Rust/Rust-like code changes in Indexer, merge logic, and tests; test-driven development; documentation updates; code reviews and release-note alignment.
