Subject [jira] [Commented] (DERBY-4115) Provide a way to drop statistics information
Date Mon, 23 Apr 2012 18:44:33 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13259826#comment-13259826
] 

Mamta A. Satoor commented on DERBY-4115:
----------------------------------------

Are we talking about dropping statistics for a specific table or all the tables in a given
schema? I think either could be implemented but wanted to double check the scope of the procedure.

> 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.
