2. Add API for showing current queries and kill query.

3. Support read/write emoji of UTF16 via ODBC Table.

Improvements

• Support HDFS HA mode when query Iceberg Table.

• Support query hive data created by Tez Engine.

• Add Ali OSS as hive external support.

2. Add support for string and text type in Spark Load.

3. Add reuse block in non-vectorized engine, and have 50% performance improvement in some cases. #11392

4. Improve like or regex performance.

5. Disable tcmalloc's aggressive_memory_decommit which will have 40% performance gains in load or query.

Currently, it is a config, you can change it by set config tc_enable_aggressive_memory_decommit.

Bug Fix

1. Some issues about FE that will cause fe failure or data corrupt.

• Add reserved disk config to avoid too many reserved BDB-JE files.(Serious) In an HA environment, BDB JE will retains as many reserved files. The BDB-je log doesn't delete until approaching a disk limit.

• Fix fatal bug in BDB-JE which will cause FE replica could not start correctly or data corrupted. (Serious)

2. Fe will hang on waitFor_rpc during query and BE will hang in high concurrent scenarios.

#12459 #12458 #12392

3. A fatal issue in vectorized storage engine which will cause wrong result. (Serious)

#11754 #11694

4. Lots of planner related issues that will cause BE core or in abnormal state.
