> Key: ISIS-573
> URL: https://issues.apache.org/jira/browse/ISIS-573
> Project: Isis
> Issue Type: New Feature
> Components: Core, Objectstore: JDO
> Affects Versions: objectstore-jdo-1.1.0, core-1.2.0
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Fix For: objectstore-jdo-1.5.0, core-1.5.0

> In DN, this is done using:
> query.addExtension("datanucleus.query.results.cached", "true");
> query.addExtension("datanucleus.query.resultCache.validateObjects", "false");
> So, need to figure out how to set up these properties on queries by
> repositories of immutable facets. But this could probably be done
> transparently.
> NB: for these cache results to hang around and not get garbage collected,
> would also need to set the global config parm:
> datanucleus.cache.queryResult.type=strong
> ... its default value is weak.
