StarRocks/starrocks 3.5.2 on GitHub

Release Date: July 18, 2025

Collected NDV (number of distinct values) statistics for ARRAY columns to improve query plan accuracy. #60623
Disabled replica balancing for Colocate tables and tablet scheduling in Shared-data clusters to reduce unnecessary log output. #60737
Optimized Catalog access workflow: FE now delays accessing external data sources asynchronously at startup to prevent hanging due to external service unavailability. #60614
Added session variable enable_predicate_expr_reuse to control predicate pushdown. #60603
Supports a retry mechanism when fetching Kafka partition information fails. #60513
Removed the restriction requiring exact mapping of partition columns between materialized views and base tables. #60565
Supports building Runtime In-Filters to enhance aggregation performance by filtering data during aggregation. #59288

Fixed the following issues:

COUNT DISTINCT queries crash due to low-cardinality optimization for multiple columns. #60664
Incorrect matching of global UDFs when multiple functions share the same name. #60550
Null pointer exception (NPE) issue during Stream Load import. #60755
Null pointer exception (NPE) issue when starting FE during a recovery from a cluster snapshot. #60604
BE crash caused by column mode mismatch when processing short-circuit queries with out-of-order values. #60466
Session variables set via PROPERTIES in SUBMIT TASK statements did not take effect. #60584
Incorrect results for SELECT min/max queries under specific conditions. #60601
Incorrect bucket pruning when the left side of a predicate is a function, leading to incorrect query results. #60467
Crash for queries against a non-existent query_id via Arrow Flight SQL. #60497

The default value of lake_compaction_allow_partial_success is set to true. Compaction operations can now be marked as successful even if partially completed, preventing blockage of subsequent compaction tasks. #60643
