Release 3.2.1 · StarRocks/starrocks

Release date: December 21, 2023

Supports reading Hive Catalog tables and file external tables in Avro, SequenceFile, and RCFile formats through Java Native Interface (JNI).

Added a view object_dependencies to the database sys. It contains the lineage information of asynchronous materialized views. #35060
Supports creating synchronous materialized views with the WHERE clause.
Supports partition-level incremental refresh for asynchronous materialized views created upon Iceberg catalogs.
[Preview] Supports creating asynchronous materialized views based on tables in a Paimon catalog with partition-level refresh.

Supports the prepared statement. It allows better performance for processing high-concurrency point lookup queries. It also prevents SQL injection effectively.
Supports the following Bitmap functions: subdivide_bitmap, bitmap_from_binary, and bitmap_to_binary.
Supports the Array function array_unique_agg.

Added a new metric max_tablet_rowset_num for setting the maximum allowed number of rowsets. This metric helps detect possible compaction issues and thus reduces the occurrences of the error "too many versions". #36539

A new BE configuration item enable_stream_load_verbose_log is added. The default value is false. With this parameter set to true, StarRocks can record the HTTP requests and responses for Stream Load jobs, making troubleshooting easier. #36113

Upgraded the default GC algorithm in JDK8 to G1. #37268
A new value option GROUP_CONCAT_LEGACY is added to the session variable sql_mode to provide compatibility with the implementation logic of the group_concat function in versions earlier than v2.5. #36150
The authentication information aws.s3.access_key and aws.s3.access_secret for AWS S3 in Broker Load jobs are hidden in audit logs. #36571
The be_tablets view in the information_schema database provides a new field INDEX_DISK, which records the disk usage (measured in bytes) of persistent indexes. #35615
The result returned by the SHOW ROUTINE LOAD statement provides a new field OtherMsg, which shows information about the last failed task. #35806

Fixed the following issues:

The BEs crash if users create persistent indexes in the event of data corruption.#30841
The array_distinct function occasionally causes the BEs to crash. #36377
After the DISTINCT window operator pushdown feature is enabled, errors are reported if SELECT DISTINCT operations are performed on the complex expressions of the columns computed by window functions. #36357
Some S3-compatible object storage returns duplicate files, causing the BEs to crash. #36103
