> Our environment has 2 local infinispan/jgroups clusters with a jgroups relay cluster to handle geographic failover. Our sites are geographically distant over a WAN. Currently DistributedExecutorService's submitEverywhere() sends Callables to every node in both local clusters. We would rather have additional methods provided to DistributedExecutorService to constrain submission on Callables to the same/local site.
> Currently I have extended DefaultExecutorService with my own TopologyAwareExecutorService and added a submitSameSite() method using the TopologyAwareAddress.isSameSite(). I did need to patch DistributedRunnableFuture in DefaultExecutorService to mark it protected vs. private.
> This could be extended to also provide submitSameRack() & submitSameMachine() though currently we don't have a use case for that.
