public class DistCacheStoreInterceptor
extends CacheStoreInterceptor

Cache store interceptor specific for the distribution cache mode. Put operations has been modified in such way that if they put operation is the result of an L1 put, storing in the cache store is ignore. This is done so that immortal entries that get converted into mortal ones when putting into L1 don't get propagated to the cache store.

Secondly, in a replicated environment where a shared cache store is used, the node in which the cache operation is executed is the one responsible for interacting with the cache. This doesn't work with distributed mode and instead, in a shared cache store situation, the first owner of the key is the one responsible for storing it.

In the particular case of putAll(), individual keys are checked and if a shared cache store environment has been configured, only the first owner of that key will actually store it to the cache store. In a unshared environment though, only those nodes that are owners of the key would store it to their local cache stores.
