> Key: CONTINUUM-2764
> URL: https://issues.apache.org/jira/browse/CONTINUUM-2764
> Project: Continuum
> Issue Type: Task
> Reporter: Brent N Atkinson
> Assignee: Brent N Atkinson
> Fix For: 1.5.0
>
>
> Upgrade the derby embedded driver that Continuum uses for its bundled
> database so that it can be tuned for improved performance. The version
> currently bundled does not have the ability to compute table statistics and
> the cost-based optimizer does not always select intelligent execution plans
> when there are useful indices to use.
> Later versions of the derby driver should be able to run against older
> databases using the soft-upgrade feature. To gain enhanced capabilities it
> will require doing a hard-upgrade. Completion of this task would make it
> possible to improve Continuum's performance by tuning indexes and computing
> statistics on tables. It will not necessarily make the application faster
> immediately.
