Performance regression tests should populate tables before creating indexes
---------------------------------------------------------------------------
Key: DERBY-5067
URL: https://issues.apache.org/jira/browse/DERBY-5067
Project: Derby
Issue Type: Improvement
Components: Test
Affects Versions: 10.8.0.0
Reporter: Knut Anders Hatlen
Assignee: Knut Anders Hatlen
I've noticed that the results from some of the performance regression tests
have become more unstable the last two weeks. See for example here:
http://home.online.no/~olmsan/derby/perf/select_30d.html
I suspect it's because the automatic index statistics thread is running (the
instability started at about the same time as it was enabled). We should make
the test clients create indexes after the tables have been populated so that
the statistics will be up to date and no work in the background is needed.
