----------------------------------------
Hi Rick,
This looks very much like DERBY-4940?
And did you mean to write possibly add *new* knobs?
> 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.
