Within a single Riak cluster, nodes communicate with each other using the Erlang distribution protocol. There are a number of reasons within Riak's design -- this just being one of them -- why spreading a Riak cluster across a wide area is not recommended. The Riak Enterprise system (http://basho.com/products/riak-overview/) uses an entirely different protocol for managing long-haul communication, and also uses a different methodology. In that system we do not spread a single cluster widely, but rather create a topology of one cluster per datacenter, with each of those connected to each other. -Justin _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
