Subject [jira] [Commented] (HBASE-3842) Refactor Coprocessor Compaction API
Date Mon, 02 May 2011 19:45:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13027795#comment-13027795

stack commented on HBASE-3842:
------------------------------

I like passing CompactionRequest notion (and it gives you access to Store if you need it).

You could do an Interface to narrow what CPs can access.  There may be concurrency/perf reasons
for not letting CPs have direct access. 

I have no strong opinion on it N.

> After HBASE-3797, the compaction logic flow has been significantly altered.  Because
of this, the current compaction coprocessor API is insufficient for gaining full insight into
compaction requests/results.  Refactor coprocessor API after HBASE-3797 is committed to be
more extensible and increase visibility.
