Improvement
- Memory usage is optimized. Users can specify the label_keep_max_num parameter to control the maximum number of loading jobs to retain within a period of time. This prevents full GC caused by high memory usage of FE during frequent data loading. #2410
BugFix
The following bugs are fixed:
- BE nodes fail when the column decoder encounters an exception. #3510
- Auto __op mapping does not take effect when jsonpaths is specified in the command used for loading JSON data. #3405
- BE nodes fail because the source data changes during data loading using Broker Load. #3481
- Some SQL statements report errors after materialized views are created. #3053
- Query may fail if an SQL clause contains a predicate that supports global dictionary for low-cardinality optimization and a predicate that does not. #3421
