Tune the istat knobs and possibly add existing knobs
----------------------------------------------------
Key: DERBY-5048
URL: https://issues.apache.org/jira/browse/DERBY-5048
Project: Derby
Issue Type: Improvement
Components: SQL, Store, Test
Affects Versions: 10.8.0.0
Reporter: Rick Hillegas
There is a discussion about reasonable defaults for the undocumented istat
knobs and about whether additional knobs are needed:
http://old.nabble.com/forum/Search.jtp?forum=105&local=y&query=question+about+istats+thresholds
This issue is a place to continue those discussions and, if necessary, to hang
patches. At the moment, we are still planning to not document these knobs.
Instead, we would like to gain experience about how istat behaves in the wild.
From that experience, we hope to figure out whether these are the right knobs,
how to set reasonable defaults for them, and whether we should document how to
override Derby's defaults.
