StarRocks/starrocks 3.4.3 on GitHub

Release Date: April 30, 2025

Routine Load and Stream Load support the use of Lambda expressions in the columns parameter for complex column data extraction. array_filter/map_filter can be used to filter and extract ARRAY/MAP data. Complex filtering and extraction of JSON data can be achieved by combining the cast function to convert JSON array/JSON object to ARRAY and MAP types. For example, COLUMNS (js, col=array_filter(i -> json_query(i, '$.type')=='t1', cast(js as Array<JSON>))[1]) can extract the first JSON object from the JSON array js where type is t1. #58149
Supports converting JSON objects to MAP type using the cast function, combined with map_filter to extract items from the JSON object that meet specific conditions. For example, map_filter((k, v) -> json_query(v, '$.type') == 't1', cast(js AS MAP<String, JSON>)) can extract the JSON object from js where type is t1. #58045
LIMIT is now supported when querying the information_schema.task_runs view. #57404

The following issues have been fixed:

Queries against ORC format Hive tables are returned with an error OrcChunkReader::lazy_seek_to failed. reason = bad read in RleDecoderV2: :readByte. #57454
RuntimeFilter from the upper layer could not be pushed down when querying Iceberg tables that contain Equality Delete files. #57651
Enabling the spill-to-disk pre-aggregation strategy causes queries to fail. #58022
Queries are returned with an error ConstantRef-cmp-ConstantRef not supported here, null != 111 should be eliminated earlier. #57735
Query timeout with the query_queue_pending_timeout_second parameter while the Query Queue feature is not enabled. #57719
