Subject [jira] [Commented] (HBASE-5365) [book] adding description of compaction file selection to refGuide in Arch/Regions/Store
Date Thu, 09 Feb 2012 19:29:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204759#comment-13204759

Doug Meil commented on HBASE-5365:
----------------------------------

Thanks!

Yeah, the "F" in "10F" is float.  I should probably just take the F out because it looks like
a typo.

As for the other number, actually it's  (HTableDescriptor)
{code}
  public static final long DEFAULT_MEMSTORE_FLUSH_SIZE = 1024*1024*64L;
{code}
... not 128.  As for the 134, I had this in my notes as the default from earlier research.
 Hmmmm.

I will fix both in another ticket.
