New Features

  • [Experimental] Starting from v3.5.1, StarRocks introduces a high-performance data transfer channel based on the Apache Arrow Flight SQL protocol, comprehensively optimizing the data import channel and significantly improving transfer efficiency. This solution establishes a fully columnar data transfer pipeline from the StarRocks columnar execution engine to the client, eliminating the frequent row-column conversions and serialization overhead typically seen in traditional JDBC and ODBC interfaces, and achieving true zero-copy, low-latency, and high-throughput data transfer capabilities. #57956
  • Java Scalar UDFs (user-defined functions) now support ARRAY and MAP types as input parameters. #55356
  • Cross-node data cache sharing: Enables nodes to share cached external table data of data lakes across compute nodes via the network. If a local cache miss occurs, the system first attempts to fetch data from the caches of other nodes within the same cluster. Only if all caches miss will it re-fetch data from remote storage. This feature effectively reduces performance jitter caused by cache invalidation during elastic scaling and ensures stable query performance. A new FE configuration parameter enable_trace_historical_node controls this behavior (Default: false). #57083
  • Storage Volume adds native support for Google Cloud Storage (GCS): You can now use GCS as a backend storage volume and manage and access GCS resources through the native SDK. #58815

Improvements

  • Optimized error messages when creating Hive external tables fails. #60076
  • Optimized count(1) query performance using the file_record_count in Iceberg metadata. #60022
  • Refined the Compaction scheduling logic to avoid delayed scheduling when all subtasks succeed. #59998
  • Added JAVA_OPTS="--add-opens=java.base/java.util=ALL-UNNAMED" to BE and CN after upgrading to JDK 17. #59947
  • Supports modifying the kafka_broker_list property via the ALTER ROUTINE LOAD command when Kafka Broker endpoints change. #59787
  • Supports reducing build dependencies of the Docker base image through parameters. #59772
  • Supports accessing Azure using Managed Identity authentication. #59657
  • Improved error messages when querying external data via Files() function with duplicate path column names. #59597
  • Optimized LIMIT pushdown logic. #59265

Bug Fixes

Fixed the following issues:

  • Partition pruning issue when queries include Max and Min aggregations and empty partitions. #60162
  • Incorrect query results when rewriting queries with materialized views due to missing NULL partitions. #60087
  • Refresh errors on Iceberg external tables when using partition expressions based on str2date. #60089
  • Incorrect partition range when creating temporary partitions using the START END syntax. #60014
  • Incorrect display of Routine Load metrics on non-leader FE nodes. #59985
  • BE/CN crashes when executing queries containing COUNT(*) window functions. #60003
  • Stream Load failures when the target table name contains Chinese characters. #59722
  • Overall loading failures to triple-replica tables when loading to a secondary replica fails. #59762
  • Missing parameters in SHOW CREATE VIEW output. #59714

Behavior Changes

  • Some FE metrics include the is_leader label. #59883
