Improvements
- Optimized the data loading performance and reduced long tail latency by reconstructing part of the hotspot code and reducing lock granularity. #6641
- Added the CPU and memory usage information of the machines on which BEs are deployed for each query to the FE audit log. #6208 #6209
- Supported JSON data types in the tables that use the Primary Key model and tables that use the Unique Key model. #6544
- Reduced FEs load by reducing lock granularity and deduplicating BE report requests. Optimized the report performance when a large number of BEs are deployed, and solved the issue of Routine Load tasks getting stuck in a large cluster. #6293
Bug Fixes
The following bugs are fixed:
- An error occurs when StarRocks parses the escape characters specified in the SHOW FULL TABLES FROM DatabaseName statement. #6559
- FE disk space usage rises sharply (Fix this bug by rolling back the BDBJE version). #6708
