Subject [jira] [Commented] (DERBY-5445) Enhance existing concurrency test to stress sequence generators to also stress identity columns
Date Wed, 05 Oct 2011 20:08:29 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5445?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121422#comment-13121422

Mamta A. Satoor commented on DERBY-5445:
----------------------------------------

I was wondering how often does java org.apache.derbyTesting.perf.clients.Runner get run? Don't
think it is part of junit suite. Does it get run as part of a new release process?

> DERBY-4565 added a concurrency test for sequence generators to test the possible race
condition for allocating a new range of pre-allocated numbers for the sequence. I have been
looking at enhancing that test to provide similar test for identity columns. I plan to add
another command line parameter to the test which will run the concurrency test to stress identity
column generator.
