[jira] Created: (DERBY-4115) Provide a way to drop statistics information

Provide a way to drop statistics information
--------------------------------------------

                 Key: DERBY-4115
                 URL: https://issues.apache.org/jira/browse/DERBY-4115
             Project: Derby
          Issue Type: Improvement
    Affects Versions: 10.5.1.0, 10.6.0.0
            Reporter: Kathey Marsden


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.
