Subject [jira] [Commented] (HBASE-11120) Update documentation about major compaction algorithm
Date Fri, 23 May 2014 02:12:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14006714#comment-14006714

Misty Stanley-Jones commented on HBASE-11120:
---------------------------------------------

bq. It would be good to insert link to effect of major compaction on read results into the
section about deletes. There's description somewhere in the book already.

Do you mean 5.9.2.2. Major compactions change query results?

> [14:20:38]  <jdcryans>	 seems that there's http://hbase.apache.org/book.html#compaction
and http://hbase.apache.org/book.html#managed.compactions
> [14:20:56]  <jdcryans>	 the latter doesn't say much, except that you should manage
them
> [14:21:44]  <jdcryans>	 the former gives a good description of the _old_ selection
algo
> [14:45:25]  <jdcryans>	 this is the new selection algo since C5 / 0.96.0: https://issues.apache.org/jira/browse/HBASE-7842
