[jira] [Commented] (HBASE-7236) add per-table/per-cf configuration via metadata

["Sergey Shelukhin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13529594#comment-13529594 ] 

Sergey Shelukhin commented on HBASE-7236:
-----------------------------------------

In fact due to above inconsistency some tests that shouldn't pass, pass... TestHFileArchiving has very low flushing which, if it were to be read correclty by split policy, would cause the region in the test to split, causing failure. 
But now the config is just ignored by policy so all is good because it uses the default. In fact it probably always uses the default unless set on HTD.

> Regardless of the compaction policy, it makes sense to have separate configuration for compactions for different tables and column families, as their access patterns and workloads can be different. In particular, for tiered compactions that are being ported from 0.89-fb branch it is necessary to have, to use it properly.
> We might want to add support for compaction configuration via metadata on table/cf.
