Manik and I agreed on API we need in DistributedCallable:
Map<String, Set<K>> getRelatedKeys();
void mappedToNode(CacheManager cm);
I will update the document accordingly.
Simple: the environment first calls getRelatedKeys(), and the impl passes back the keys it would need. The env then maps the task to a node, based on locating the keys, serializes and pushes the callable to the assigned node. The assigned node then calls mappedToNode() so that the impl has a ref to the cache in the local VM. After that, call() is invoked.On 2 Aug 2010, at 15:31, vblagoje@redhat.com wrote:I would love to make it this simple but how does execution environment know which cache to pass in mappedToNode?

I still don't see why you need to pass it the cache manager. Perhaps:
DistributedCallable {
Set<K> getRelatedKeys();
void mappedToNode(Cache<K, V> cache);
}
