> We should experiment the effectiveness of this feature. Instead of a peer sending message to each of the peers that logically a part of a group(active vertices of graph, members of group in a cluster, etc.)
> The API could be:
> {code}
> peer.sendMessageToGroup(String group, Writable message);
> {code}
> This should result in finding all the peers that are members of that group and send message to each of the peers in the group.
> Peers can change their membership status using the following API.
> The guarantee of the group membership is ensured only in the next superstep.
> {code}
> peer.registerWithGroup(String group, Writable message);
> peer.deregisterFromGroup(String group, Writable message);
> {code}
> For now we can try using Zookeeper for this solution.
