Worked on the luong-komorebi/connector-x repository to enhance data source initialization and cross-database query reliability. Developed support for pre-execution SQL queries in read_sql, enabling setup statements to run before main queries on PostgreSQL and MySQL sources. Improved test suite stability by aligning PostgreSQL row-count expectations and standardizing the test harness, reducing flakiness in CI. Centralized pre-execution query logic with a default Source trait implementation in Rust, replacing per-source handlers and reducing boilerplate. Refactored MySQL variable naming for clarity and maintainability. Leveraged Rust, Python, and SQL to deliver robust data engineering solutions and improve long-term code quality.

Feb 1, 2025February 2025: Consolidated and standardized pre-execution queries across data sources in connector-x, introducing a default Source trait implementation to replace per-source unimplemented handlers and adding tests for partitioned pre-execution queries in MySQL and PostgreSQL. Also renamed MySQL data source variables for clarity, improving maintainability and reducing future technical debt. These changes improve reliability of cross-source query behavior and set the stage for easier onboarding and future enhancements.

Jan 1, 2025January 2025: For luong-komorebi/connector-x, delivered a targeted feature to run setup SQL before the main query via pre_execution_queries for read_sql on PostgreSQL and MySQL sources. Stabilized test results by aligning PostgreSQL row-count expectations and standardizing the test harness, reducing flaky tests. Performed code quality and configuration cleanup by formatting Rust code and reverting the default Cargo feature flag to stabilize builds and improve readability. These work items collectively improve data source initialization reliability, CI stability, and long-term maintainability.
