Upgrade Notice
Known Issues
Behavior Changed
The default value of the BE configuration item
high_priority_flush_thread_num_per_store
is changed from 1 to 6 (#14775)To improve the write efficiency of Routine Load.
The default value of the FE configuration item
enable_new_load_scan_node
is changed to true. (#14808)Import tasks will be performed using the new File Scan Node. No impact on users.
Delete the FE configuration item
enable_multi_catalog
.The Multi-Catalog function is enabled by default.
Decimal v3 precision display changes.
When the user uses the Decimal V3 type, the result will be returned according to the actual defined precision. And support the precision derivation of function transformation.
The vectorized execution engine is forced to be enabled by default (#15213)
The session variable
enable_vectorized_engine
will no longer take effect. Enabled by default.To make it valid again, set the FE configuration item
disable_enable_vectorized_engine
to false, and restart FE to makeenable_vectorized_engine
valid again.Big Thanks
