Worked on the aws-athena-query-federation repository to deliver scalable metadata pagination for database connectors, focusing on the Snowflake and JDBC integrations. Developed chunked table retrieval using Java and SQL, introducing token-based next-page logic and updating the JdbcMetadataHandler to support efficient pagination. Enhanced the backend by implementing a centralized PaginationHelper, standardizing pagination logic across connectors, and introducing a fallback strategy for JDBC metadata listings to ensure robust handling of large catalogs. Emphasized maintainability and reliability through refactoring and unit testing, resulting in improved performance and user experience when enumerating metadata in distributed data environments without addressing major bug fixes.

Apr 1, 2025April 2025: Focused on delivering scalable metadata pagination for the Snowflake connector in the aws-athena-query-federation repo. Implemented chunked table retrieval via listPaginatedTables, added token-based next-page logic, and updated the JdbcMetadataHandler to support pagination. No major bugs fixed this month. These changes improve performance and user experience when enumerating large catalogs (faster, lower memory usage) and set the foundation for scalable metadata operations in client integrations.
