-------------------------------------------
Summary: Upgrade to latest version of derby
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.
