[infinispan-dev] cache loader/preload

[Galder Zamarreño]

JSR-107 comes with an interesting twist on preloading. It's not really a cache writer/loader configuration, but instead there's a high level loadAll API in Cache to load data from a cache store [1]. I wonder if it'd make sure for us to go that way too, although the main problem we have is that once a cache is retrieved from the cache manager, it's already started, and our current preloading strategy works as part of the start() procedure.

Also, JSR-107 seems to be enable loading of a subset of keys and I'm not sure how you can load all entries in the store.

In spite of this, it's something worth bearing in mind for preloading discussions...
