3.3.8

Release date: January 3, 2025

Improvements

  • Added a cluster idle API to assist in determining cluster status. #53850
  • Included node information and histogram metrics in JSON metrics. #53735
  • Optimized the MemTable for Primary Key tables in shared-data clusters. #54178
  • Optimized memory usage and statistics for Primary Key tables in shared-data clusters. #54358
  • Introduced a limit on the number of partitions scanned per node for queries requiring full-table or large-scale partition scans, enhancing system stability by reducing scanning pressure on individual BE or CN nodes. #53747
  • Supports collecting statistics of Paimon tables. #52858
  • Supports configuration of S3 client request timeout for shared-data clusters. #54211

Bug Fixes

Fixed the following issues:

  • BE crashes caused by inconsistencies in the DelVec of Primary Key tables. #53460
  • Issues with lock release of Primary Key tables in shared-data clusters. #53878
  • Errors of UDFs nested in functions are not returned in query failures. #44297
  • Transactions are blocked at the Decommission phase because they depend on the original replicas. #49349
  • Queries against Delta Lake tables use relative paths instead of filenames for file retrieval. #53949
  • An error is returned when querying Delta Lake Shallow Clone tables. #54044
  • Case sensitivity issues when reading Paimon using JNI. #54041
  • An error is returned during INSERT OVERWRITE operations on Hive tables created in Hive. #53792
  • SHOW TABLE STATUS command does not validate view privileges. #53811
  • Missing FE metrics. #53058
  • Memory leaks in INSERT tasks. #53809
  • Concurrency issues caused by missing write locks in replication tasks. #54061
  • partition_ttl of tables in the statistics database does not take effect. #54398
  • Query Cache-related issues:
    • Crashes when Query Cache is enabled with Group Execution. #54363
    • Runtime Filter crashes. #54305
  • Issues with materialized view Union Rewrite. #54293
  • Missing padding in string updates for partial updates in Primary Key tables. #54182
  • Incorrect execution plans for max(count(distinct)) when low-cardinality optimization is enabled. #53403
  • Issues with changing the excluded_refresh_tables parameter of materialized views. #53394

Behavior Changes

  • Changed the default value of persistent_index_type for Primary Key tables in shared-data clusters to CLOUD_NATIVE, that is, enabled Persistent Index by default. #52209
