Worked on the datametica/calcite repository to enhance SQL generation and planning capabilities, focusing on backend development and data engineering. Delivered support for Databricks table-valued functions and introduced trait-based integration to enable cross-dialect SQL extensibility using Java and SQL. Addressed reliability by fixing duplicate alias handling in CTE joins and corrected boolean type coercion for the BigQuery dialect, improving query correctness and reducing runtime errors. Implemented flexible row-type customization across Calcite’s planning components, allowing for diverse data types and entity naming. The work emphasized code refactoring, database optimization, and robust SQL dialect implementation to support evolving analytics requirements.
