Malcolm,
Cayenne already supports this via query caching. Check
SelectQuery.setCachePolicy(..). The policy can be either of
QueryMetadata.LOCAL_CACHE, QueryMetadata.LOCAL_CACHE_REFRESH,
QueryMetadata.SHARED_CACHE, QueryMetadata.SHARED_CACHE_REFRESH (should
probably define them as enums in 3.0).

Support Entity/Table scope caching

Key: CAY-925
URL: https://issues.apache.org/cayenne/browse/CAY-925
Project: Cayenne
Issue Type: New Feature
Components: Cayenne Core Library, CayenneModeler GUI
Affects Versions: 3.0
Reporter: Malcolm Edgar
Assignee: Andrus Adamchik
On most of our projects we do not use caching, because of the size
of the databases, and or issues of multiple applications writing to
the database. However one feature we would really like is to be
able to specify that individual tables/entities are cached in memory
by Cayenne.
This is typically for UI lookup values which change very
infrequently, or deployment properties which also change
infrequently. By caching this information in memory we can
significantly reduce the number of requests made to the database and
improve application performance.
