4.1.1

Release Date: May 29, 2026

Container Image Issue (v4.1.0): Due to an unstable load order issue in the v4.1.0 container image, BE processes may fail to start reliably in container environments. Container environment users should NOT upgrade to v4.1.0; use v4.1.1, which includes the fix (#71825).

Downgrade Notes: After upgrading StarRocks to v4.1, DO NOT downgrade to any v4.0 version below v4.0.6. Due to internal data-layout changes in v4.1 (tablet splitting and distribution), downgrade from v4.1 is only supported to v4.0.6 or later.

Behavior Changes

  • The Hive connector now uses a native C++ Avro scanner instead of the JNI Avro scanner by default. #73237 #73569
  • Query rewrite over INCREMENTAL/AUTO materialized views is now disabled, and FORCE refresh and partition refresh are rejected for INCREMENTAL/AUTO materialized views. #72890 #72336 #71355

Improvements

  • Java UDF/UDAF/UDTF now support more types: STRUCT arguments and return values for UDAF/UDTF, nested ARRAY/MAP types, DATE/DATETIME, DECIMAL, and varargs. #72911 #72283 #72337 #72208 #68596
  • Scalar UDFs now support STRUCT arguments. #72620
  • Python UDFs now support nested ARRAY/MAP types. #72210
  • UDAFs are now loaded and initialized once and reused across queries, reducing per-query overhead. #72038
  • Replaced the JNI Avro scanner with a native C++ scanner for the Hive connector, with direct binary decoding and support for avro.schema.literal and avro.schema.url. #73237 #73283 #73257 #73569
  • Supports the Trino WITH clause in CTAS statements. #71960
  • Completed Iceberg timestamptz partition transform support on the sink path. #73397
  • Enabled TopN runtime filter pushdown for Iceberg table aggregation. #72332
  • Supports Iceberg datetime min/max optimization. #71870
  • Allows HDFS HA configuration passthrough in Catalog and BE to support accessing multiple HDFS clusters. #71521
  • Added a partition scan number limit for external table queries. #68480
  • Fails fast for unsupported Iceberg V3 features. #70242
  • Supports csv.enclose and csv.escape for CSV exports via INSERT INTO FILES. #71589
  • Added the enable_push_down_schema INSERT property for full schema push-down to files(). #70978
  • Routine Load jobs are now paused on non-retryable errors (for example, primary key size exceeded). #71161
  • Supports join reorder for complex expressions from two children. #71615
  • Improved CBO statistics estimation, including MCV/null-fraction propagation for date_trunc, array_map, CASE WHEN, IS NULL, UNION, and constants. #72233 #70372 #70221 #70865 #70989 #71000
  • Improved skew join detection: skew is only detected when all join keys are skewed, and a force_group_by_skew_eliminate_when_skewed switch was added to force the skew rule. #72753 #71382
  • Supports constant folding for regexp_replace in the FE. #70804
  • Optimized MIN/MAX on date partition columns with constant partition values. #69880
  • Introduced the SCHEDULE keyword as a synonym for ASYNC in materialized view refresh. #72329

  • Supports conditional update for Lake column-mode partial update. #71961
  • Parallelized partial-update publish, persistent index initialization, and SSTable opening to improve ingestion throughput. #71652 #71217 #72112 #71145 #72986
  • Supports DCG file synchronization during shared-nothing to shared-data replication. #69339
  • Supports schema evolution for widening VARCHAR length on both key and non-key columns. #70747
  • Added the snapshot_meta.json marker for cluster snapshot integrity checks. #71209

  • Supports auditing queried relations in the audit log. #71596
  • Added session variables for MySQL binary result encoding. #71415
  • Added metrics for better observability, including tablet_num for shared-data clusters, MemtableIOSpeed, staros_shard_count, and Iceberg metadata-table query metrics. #71444 #69842 #73096 #70825
  • Added the FE configuration deploy_serialization_min_thread_pool_size. #72274
  • Added the tablet_reshard_enable_tablet_merge configuration to disable MergeTabletJob creation. #70906
