Description

It would be nice to make query cache an independent module that can be managed externally. There have been some discussions on that in the past [1], and now I have a real-life case where this can be tested.

[1] http://objectstyle.org/cayenne/lists/cayenne-devel/2006/04/0250.html

Here is the scope of this feature:

• (DONE - LRUMap and OSCache implementations) Pluggable cache for queries (local and shared) that can be managed externally
• determine cache key automatically. I.e. if a query has cache enabled, but no "name" specifiied, cache key should be build on the fly.
• OSCache provider - support mapping of cache groups (entities are groups) to cache policies in OSCache
• OSCache provider - support mapping individual query names to cache policies.
• hookup ObjectStore and DataRowStore object caches with shared cache.
