Subject [jira] Commented: (DERBY-2249) Place holder to attach the long running test which will test Derby's improved optimizer
Date Thu, 15 Feb 2007 21:18:06 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12473517

Daniel John Debrunner commented on DERBY-2249:

Not sure it falls into the category of a "basic" performance test, those seem to be ones that
test a specific action, not a broad range of optimizer issues like this test.

Maybe the split between "perf" and "system" is arbitrary. I've been thinking of tests like
oe (system/oe) as toolkits. They provide building blocks that can be used a number of ways,
as a performance test, as a stress test, as a system test, etc. Maybe this test is the same.
It could be used to compare the performance of queries against releases, or it could be used
to stress the optimizer by running for several weeks.
Trying to pre-assign specific tests for the code I think is a mistake,implement one use but
allow others.
