MisterWang updated HBASE-28654:
-------------------------------
Description:
As is known to all, the compact processes generate a certain amount of I/O. But
in some cases, not being compact in time does not affect online services.
For example, in the scenario where the TTL time of a table is short, there are
more writes than reads. To ensure write performance and reduce cluster I/O
pressure, Only expired files are removed in the compact process is a good idea.
Another usage scenario: Tables have primary and backup, and the backup table
can add this table attribute to reduce the compact IO of the backup cluster.
Optimization solution: Add a table attribute for the HBase table
