jackrabbit with SimpleDbPersistenceManager, can it use filesystem cache?

[Phillip Rhodes <sp...@rhoderunner.com>]

I am considering porting my home-grown hibernate/springframework based image content/gallery system to use jackrabbit on the back end.

I would like to use the SimpleDbPersistenceManager because my application runs on multiple machines, but at the same time, I do not want to be pulling blobs out of the db in realtime for every request.  

Is there a way to configure jackrabbit to cache images/content from the filesystem after it pulls them from the database (SimpleDbPersistenceManager )?

Thanks!

there's already a layer in jackrabbit's core that caches items read from the
persistence layer (see
http://jackrabbit.apache.org/api-1/org/apache/jackrabbit/core/state/SharedItemStateManager.html).

you might also consider setting "externalBLOBs=true" (see
http://jackrabbit.apache.org/api-1/org/apache/jackrabbit/core/state/db/SimpleDbPersistenceManager.html).
