Release date: July 23, 2026

Behavior Changes

• CREATE DATABASE IF NOT EXISTS on Iceberg REST catalogs now succeeds silently when the database already exists, instead of raising an error. #75017
• Iceberg REST catalogs with vended credentials now cache Table objects and keep their credentials refreshed on access, instead of bypassing the cache and re-fetching from the REST catalog/Lake Formation on every getTable() call, which could trigger AWS Rate exceeded errors. #75431
• GIN inverted-index-accelerated NOT MATCH predicates no longer return rows with a NULL value, matching SQL three-valued-logic semantics. #75578

Improvements

• Added the FE metric txn_max_committed_pending_publish_ms, a per-database gauge reporting the longest time a committed transaction has been pending publish, to help diagnose stuck or lagging version publishing. #75025
• Enforced the query memory limit when a column is upgraded (widened) during window-function aggregation in Analytor, instead of letting it grow unbounded. #75821
• Removed useless per-rowid seeks in the array-column offsets-only read path used by array_length()/cardinality(). #75861

Bug fixes

The following issues have been fixed:

• Several wrong-result issues: EliminateSortColumnWithEqualityPredicateRule dropping the global LIMIT under concurrency; SplitJoinORToUnionRule producing duplicate rows for a null-safe-equal (<=>) JOIN ON p1 OR p2; JIT codegen truncating LARGEINT literals >= 2^64 to 64 bits; array_map/transform silently dropping NULL rows when all non-null input arrays were empty; nested dictionary expressions rebuilt inconsistently across exchange fragments causing dict-decode failures; and a LIKE pattern with the _ wildcard returning wrong rows on a GIN inverted index. #74983 #75038 #75137 #75141 #75246 #75551
• Join-reorder column pruning could drop a column still referenced by a predicate, causing a missing statistic of col planning error, and JoinTuningGuide could lose predicateCommonOperators when rebuilding a join, failing plan validation. #74791 #75773
• Sync materialized view/rollup rewrite could lose a rollup column when a query aggregated the same base column twice (e.g. min(c) and max(c)), and async materialized view rewrite could serve stale results after an Iceberg base table's rollback_to_snapshot. #75528 #75924
• PARTITION-TOP-N could rewrite its partition-by column to a dictionary slot that no longer existed, failing with a slot_id not found error. #75956
• An NPE collecting view tables when a SECURITY INVOKER view's stored definition contains a CTE. #74813
• Three FE metadata-lock correctness races around DROP PERSISTENT INDEX, RestoreJob post-restore handling, and related unlocked paths. #74968
• A race between FE EOS-cancel and BE stage-2 deploy could mark a fully successful query as canceled. #75009
• ApplyTuningGuideRule could throw UnsupportedOperationException when an earlier rewrite produced an OptExpression with an immutable input list. #70785
• BE/CN crashes: a null driver_executor when a cancel RPC arrives before pipeline start; a use-after-free in the spill partition-sort-sink cancel path; a heap-use-after-free in OrderedPartitionExchanger for a skew-hinted window function at DOP>1; an NLJoin crash from a build-side column nullability mismatch; a StructColumn field-count mismatch in UNNEST output; a crash loop reading a flat-JSON column that changed from NOT NULL to nullable during compaction; an uncaught memory-allocation exception in NLJoinProbeOperator; a crash in primary-key auto-increment partial-update apply; and a crash rewriting predicates inside an array_map lambda during scan-predicate pushdown. #75030 #75140 #75279 #75343 #75445 #75680 #75788 #76119 #76380
• histogram() crashed (or silently mis-bucketed values) on a non-positive bucket_num instead of raising a clear error, and bar() could grow an unbounded string for a negative or huge width argument, exhausting BE memory. #75041 #75143
• A query using unnest over array columns could exceed query_mem_limit and get the BE OOM-killed instead of failing just that query. #75179
• A second-order SQL injection in the information_schema.task_runs TASK_NAME/QUERY_ID predicate lookup. #75520
• SHOW CREATE ROUTINE LOAD could emit a spurious leading comma before the first load-desc clause, and an unescaped jsonpaths value, producing non-runnable DDL. #75522 #75755
• Shared-data (lake) SHOW PARTITIONS and information_schema.partitions_meta reported every physical partition's bucket count as the table-level default instead of its own bucket count. #75734
• Several dependency CVEs by upgrading jackson-databind and Netty. #75373 #76555
• Batched TabletInvertedIndex write-lock acquisition in markTabletsForceDelete, reducing lock churn when force-deleting many tablets at once. #75616
• Batched tablet inverted-index writes in the insert-overwrite path. #75923
• Skipped an unnecessary remote clear_parent_path call when a load spill never used remote storage. #76224
• A null-padding size mismatch for missing columns in ParquetScanner so padded rows match the actual per-batch chunk size instead of the whole Parquet/Arrow batch size. #75981
• Vulnerable, stale transitive dependencies (old BouncyCastle, OkHttp 2.x, Tomcat, and others) that previously shipped alongside their fixed counterparts. #76097
