During June 2025, Fztang focused on enhancing stream processing quality assurance for the taosdata/TDengine repository. They developed comprehensive test coverage for Session Streams, introducing new test cases that validated trigger types and session window behaviors. Using Python scripting and SQL, Fztang established an end-to-end test environment, setting up databases, super tables, and stream trigger tables to simulate diverse configurations. Their work emphasized early regression detection and improved test reliability by validating data output and schema correctness across multiple stream creation scenarios. This effort deepened the reliability of stream-related features, ensuring robust delivery of streaming capabilities within the TDengine platform.
