Subject [jira] [Commented] (OAK-1451) Expose index size
Date Tue, 10 Mar 2015 18:11:42 GMT

    [ https://issues.apache.org/jira/browse/OAK-1451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14355351#comment-14355351

Michael Marth commented on OAK-1451:

[~tmueller], afair we now use the index size to in the query planning. Maybe we can implement
this MBean in 1.3.x?

> At the moment some MK's disc needs are largely from the indexes. Maybe we can do something
about this, but in the meantime it would be helpful if we could expose the index sizes (num
of indexed nodes) via JMX so that they could be easily monitored.
> This would also be helpful to see at which point an index becomes useless (if the majority
of content nodes are indexed one might as well not have an index)
