Jing Zhang updated HUDI-7578:
-----------------------------
Description:
After upgrade a hudi table from 0.10 version to 0.14 version, the compaction
job become much more slower.
The hudi table is a MOR table without partition field. And the hudi table does
not do any schema evolution.
The compaction job would finished in 52 minutes using 0.14 version. But the
compaction job would finished in 25 minutes using 0.10 version.
And in the 0.14 version, the task jstack become much more complex. Including
the following content:
