Define CacheLoader for different Regions

[dandrolvorn]

I've searchend the documentary and this forum, but i cant find anything relies to this topic. It is possible to Define CacheLoader for a special region, so that my cache would be persisted in parts, not completely? Or is there a other way?

No, you're only allowed one cache loader per cache instance. You can of course create multiple cache instances in your application.

Thanks :)

This shouldn't be too hard to implement, though. You can extend cache loader with a custom one, which would filter request and delegate to JDBCCacheLoader when needed.

[dandrolvorn]

Yeah ... i thought so, but it would be dirty (my oppinion).
Whatever i use a custom CacheLoader, that writes the Cache down into a Db4o Database, written by myself.

Now i use two cache instances, one with the CacheLoader.

If you have written a db4o Cache Loader and think it may be generally useful, do you feel like contributing it to JBoss Cache?

[dandrolvorn]

Why not? :)
Should i send you the three source files? Should i pay attention to something?

[manik]

email me a patch (off trunk?) and I'll have a look. You should also create a unit test, along the lines of the BDBJECacheLoaderTest or JDBCCacheLoaderTest (just extend the base test class which does all the real work).
