Improvements

• Added transaction latency metrics to FE for observing timing across transaction stages. #64948
• Supports overwriting S3 unpartitioned Hive tables to simplify full-table rewrites in data lake scenarios. #65340
• Introduced CacheOptions to provide finer-grained control over tablet metadata caching. #65222
• Supports sample statistics collection for INSERT OVERWRITE to ensure statistics stay consistent with the latest data. #65363
• Optimized the statistics collection strategy after INSERT OVERWRITE to avoid missing or incorrect statistics due to asynchronous tablet reports. #65327
• Introduced a retention period for partitions dropped or replaced by INSERT OVERWRITE or materialized view refresh operations, keeping them in the recycle bin for a while to improve recoverability. #64779

Bug Fixes

The following issues have been fixed:

• Lock contention and concurrency issues related to LocalMetastore.truncateTable(). #65191
• Lock contention and replica check performance issues related to TabletChecker. #65312
• Incorrect error logging when changing user via HTTP SQL. #65371
• Checksum failures caused by DelVec CRC32 upgrade compatibility issues. #65442
• Tablet metadata load failures caused by RocksDB iteration timeout. #65146
• When the internal flat_path string is empty because the JSON hyper extraction path is $ or all paths are skipped, calling substr will throw an exception and cause BE crash. #65260
• The PREPARED flag in fragment execution is not correctly set. #65423
• Inaccurate write and flush metrics caused by duplicated load profile counters. #65252
• When multiple HTTP requests reuse the same TCP connection, if a non‑ExecuteSQL request arrives after an ExecuteSQL request, the HttpConnectContext cannot be unregistered at channel close, causing HTTP context leaks. #65203
• MySQL 8.0 schema introspection errors (Fixed by adding session variables default_authentication_plugin and authentication_policy). #65330
• SHOW ANALYZE STATUS errors caused by unnecessary statistics collection for temporary partitions created after partition overwrite operations. #65298
• Global Runtime Filter race in the Event Scheduler. #65200
• Data Cache is aggressively disabled because the minimum Data Cache disk size constraint is too large. #64909
• An aarch64 build issue related to the gold linker automatic fallback. #65156
