Subject [jira] [Commented] (DERBY-4115) Provide a way to drop statistics information
Date Tue, 24 Apr 2012 18:25:34 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13260783#comment-13260783

Mike Matrigali commented on DERBY-4115:
---------------------------------------

I am good with the name of the procedure, and with respect to roles and permissions I think
it should just function the same way as update statistics routine does.

> Now that DERBY-269 has been resolved,  users can update statistics, but once they do,
they are committed to using and maintaining the statistics, even if it doesn't improve performance
or they have difficulty maintaining the statistics on a regular basis.  It would be good to
have a way to drop statistics information so that users could revert to the prior behavior
if needed.
