Subject [jira] Resolved: (DERBY-4363) Add simple benchmark for measuring GROUP BY performance
Date Sat, 12 Sep 2009 21:10:57 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4363?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Bryan Pendleton resolved DERBY-4363.

       Resolution: Fixed
    Fix Version/s:

I fixed a small typo in wisconsin.java (the 'compress' argument was always being
set to 'false', ran a complete set of regression tests without problem, and submitted
this benchmark as revision 814237.

We may end up adding more types of GROUP BY statements to this benchmark
over time, but for now it seems like the work on this task is done.

the performance of GROUP BY.
