Galder Zamarreño commented on ISPN-4470:
----------------------------------------

RemoteCache.keySet() javadoc:

{quote}
    * Returns all keys in the remote server.  It'll invoke a command over the network each time this method is called.
    * If the remote cache is a distributed cache, it will retrieve all of the keys from all nodes in the cluster.
    * Please use with care for cache with large data set.
{quote}

It's clear that keySet() can retrieve keys cluster-wide.

size() should behave in a similar way, since it should not vary depending on the server that it hits. Its javadoc needs adjusting too.

> cache.keySet().size() returns the number of all keys in the cluster (even a distributed one) while cache.size() returns just local cache size (this might be different for a distributed cache)
