Jonathan Ellis commented on CASSANDRA-5400:
-------------------------------------------
We're adding endpoint as a new datatype? That sounds a little niche to commit
to supporting that forever. What's wrong with separate {{host inet, port int}}
columns?
> Allow multiple ports to gossip from a single IP address

> If a fat client is running on the same machine as a Cassandra node, the fat
> client must be allocated a new IP address. However, since the node is now a
> part of the gossip, the other nodes in the ring must be able to talk to it.
> This means that a local only address (127.0.0.n) won't actually work for the
> rest of the ring.
> This also would allow for multiple Cassandra service instances to run on a
> single machine, or from a group of machines behind a NAT.
> The change is simple in concept: instead of using an InetAddress, use a
> different class. Instead of using an InetSocketAddress, which would still tie
> us to using InetAddress, I've added a new class, "CassandraInstanceEndpoint".
> The serializer allows for reading a serialized Inet4Address or Inet6Address;
> also, the message service can still communicate with
> non-CassandraInstanceEndpoint aware code.
