Hi Guys,
I might be getting ahead of myself a bit here, but I'm going to try and turn off the default MRU store, in favour of the JCS based persistent store. I'd like to try some tests on performance without the default MRU - has anyone else tried anything similar? I've simply set the core store's role to point to the JCS store implementation.
I guess I already got ahead of you when I renamed JCSPersistentStore JCSStore just now :-) (And merged it with the AbstractJCSStore BTW). It seems to me that JCS is both and it could replace all three stores: DefaultStore, TransientStore and PersistentStore.
I have to add that this is not the whole story. We do actually need to distinguish between persistent and transient storage. Some components explicitly want to persist some data instead of just cache it for speed. But as far as caching is concerned I think it we can leave it completely up to JCS.
Some components are explicitely using the transient-store to keep data that shouldn't (or cannot) be serialized. But AFAIK, no component directly uses the persistent-store except the store itself.
So if the JCSStore includes a MRU-like memory front-end, it can simply replace the <store> component in cocoon.xconf.
