Distributed Callable with automatic filled keys in environment where current node = owner

In a distributed cache I need to process every key one time. My solution is ATM to create a distributed call and on every node walk through the keyset of the cache and process every node, where the current node is the owner.

This solution works, but is not really nice.

I'd like to have a specific Distributed callable for this or an flag/option to enable that the keys where the current node is owner are used at setEnvironment(...).
