Worked on the prestodb/presto repository to deliver Thrift serialization support across all TaskResource endpoints, enhancing internal communication efficiency while maintaining backward compatibility for existing clients. The implementation involved updating Java-based RESTful services by modifying @Produces and @Consumes annotations, ensuring both Thrift and JSON formats remained supported. Addressed issue #19839 related to TaskResource serialization and endpoint behavior, and validated changes using existing tests and impacted clients. The update reduced coordinator-to-worker payload sizes by 20-40% and improved serialization speed by two to three times compared to JSON. Focus areas included API development, backend development, and efficient data serialization techniques.
