Apr 1, 2025April 2025: Strengthened Cascades planner error handling in FoundationDB/fdb-record-layer by introducing a specific UnableToPlanException for cases when the planner cannot plan a query. This replaces the prior generic RecordCoreException and is mapped to UNSUPPORTED_OPERATION in the Relational Layer, enabling clearer signals to clients and tooling. Also fixed a potential NPE in error messaging by guarding the underlying exception message (commit 212d279da950b5cac6d799f313e6b910a2545cde).

Sep 1, 2023September 2023 (FoundationDB/fdb-record-layer) delivered key SQL-layer enhancements and reliability improvements that boost data modeling flexibility, SQL compatibility, and parser robustness. Major features include support for Array Data Types (enabling array insert/update with lexer/parser/AST updates), PreparedStatement NULL Value Support (ability to set SQL NULL via PreparedStatement), and a Case-Sensitive Schema Option (treats SQL identifiers as-is with optional quotes). Critical bug fixes addressed parsing and versioning issues, including a Minor Version Parsing Bug Fix (integers used for minor version comparisons) and DDL Grammar Ambiguities with improved error handling. A code-quality uplift was achieved through a dedicated OpenRewrite pass to improve readability and consistency. These changes collectively reduce integration risk, improve developer experience, and enable richer data modeling and SQL usage for client applications.

Jun 1, 2022June 2022 monthly summary for FoundationDB/fdb-record-layer focusing on stability, configurability, and test reliability across the relational layer. Delivered key features to unify and contract relational DB options, clarified pagination semantics, and added EXPLAIN support. Fixed critical DDL parsing edge cases and hardened autotests and connection error handling, resulting in a more robust, observable, and developer-friendly relational layer. Key outcomes: - Strengthened configuration reliability and consistency across connections and queries through unified, immutable Options and type/range contracts. - Improved query planning visibility with EXPLAIN support, enabling better performance analysis and debugging. - Clarified paging semantics by renaming ROW_LIMIT to CONTINUATION_PAGE_SIZE to avoid confusion with SQL LIMIT. - Increased test reliability via autotest improvements, better metadata handling, and adjusted query plan generation. - Hardened error reporting for non-existent databases and invalid URLs, with targeted tests to reduce incident response time.
