Subject [jira] [Commented] (HBASE-7516) Make compaction policy pluggable
Date Thu, 17 Jan 2013 18:22:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7516?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556435#comment-13556435

Sergey Shelukhin commented on HBASE-7516:
-----------------------------------------

Please see comments above...
For level compactions even things like store file management will have to be pluggable.
For many possible compaction algorithms on the other hand this change is sufficient.
We can build on top of it for leveldb; I think that on top of this change, there should be
an ability to replace CompactionPolicy/Compactor/etc. together. Including, for example for
tiered algorithm, keeping standard compactor and replacing the policy. Or the other way around.
First JIRA for that is HBASE-7603.

> Currently, the compaction selection is pluggable. It will be great to make the compaction
algorithm pluggable too so that we can implement and play with other compaction algorithms.
