March 2026 — Apache Calcite: Delivered a new SQLite POSITION function enhancement by adding FROM clause support, enabling flexible string position queries and broader SQLite compatibility. Implemented logic to handle both FROM and non-FROM cases, aligning the dialect with common SQL usage. The change is tracked under commit 2886ce17f625452574a395f597b807618734da56 for [CALCITE-7316]. No major bugs fixed this month; the focus was feature delivery. Impact: expands query expressiveness, reduces client-side workarounds, and strengthens Calcite's SQLite integration. Technologies/skills demonstrated: Java-based dialect extension, SQL parsing and optimization, Git versioning and traceability, and test coverage for dialect features.
