Peter Schuller commented on CASSANDRA-3834:
-------------------------------------------
I am talking about everything that Gossip does. Having an abstraction that
provides ring topology and remove gossip specific assumptions in the code
outside of the gossiper. It's fairly well isolated, but not entirely.
CASSANDRA-3833 is really the bigger change because it fundamentally changes the
abstraction operated upon. The current abstraction is very tied to one
particular nature of gossip - that nodes change states individually rather than
in aggregate. The arbitrary topology ticket wants to address that, and this
ticket is intended to be "prep work" that is legitimate in it's own right.

> gissip to discover ring topology.
> This is in part for CASSANDRA-3833, but is also useful because we want
> something simpler and more reliable than gossip on production
> clusters. At minimum we must be able to hit our nodes with a clue bat
> in emergencies ("no this node is NOT in state Normal damn it"), even if
> we were to normally rely on gossip.
