Worked on the datametica/calcite repository to deliver SQL Server POWER function support and modernize the codebase. Developed cross-dialect POWER handling by introducing a dedicated POWER function and aligning POWER1 semantics with SQL Server, ensuring consistent behavior across SQL dialects. Expanded automated test coverage, including BigQuery POWER1 literals, to validate interoperability and reliability. Undertook targeted refactoring to improve maintainability and testability of function logic. Additionally, upgraded dependencies by migrating from commons-lang to commons-lang3 and removing deprecated libraries, streamlining imports for better compatibility. Utilized Java, SQL, and dependency management skills to reduce technical debt and enable future enhancements.

Nov 1, 2024Month 2024-11: Delivered cross-dialect POWER support in Calcite for SQL Server, enabling consistent POWER semantics across dialects and reducing integration friction for SQL Server users. Implemented SQL Server library integration by adding a SqlLibrary enum value and registering a dedicated POWER function, and introduced POWER1 handling to mirror SQL Server behavior. Expanded automated tests to cover BigQuery POWER1 literals, validating cross-dialect consistency. Performed a targeted refactor of POWER Function handling (RMSB-106) to improve maintainability and testability. No major bugs reported/fixed this month. Overall impact: enhanced SQL Server compatibility, broader dialect interoperability, and stronger test coverage, contributing to faster delivery of reliable cross-dialect SQL. Technologies/skills demonstrated: cross-dialect function design, enum extension, function registration, test-driven development, and collaborative code refactoring.
