Subject [jira] Updated: (DERBY-4771) Continue investigation of automatic creation/update of index statistics
Date Fri, 01 Oct 2010 05:43:32 GMT

Lily Wei updated DERBY-4771:
----------------------------

    Attachment: rjall.rar

Before adding application tests, I thought I tried it with Suites.All with all the tracing
and flag set to true for the feature. UpdateStatisticsTest failed by itself on my machine.
Maybe the lcc to update the data dictionary directly from the daemon has some concurrency
issue to tweet with. I really enjoy seeing all the tracing log for this feature. That is so
great. I will try to run it with application next and understand the lcc more.
