----------------------------------------------
[~jjirsa] Moved from Patch Available to Awaiting Feedback, as your comment
gives an impression that it's not fully complete yet.
Someone will give feedback eventually, but, for context, what's missing in the
branch?
> Support "edge dcs" with more flexible gossip
> --------------------------------------------

> Key: CASSANDRA-7306
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7306
> Project: Cassandra
> Issue Type: Improvement
> Components: Distributed Metadata
> Reporter: Tupshin Harper
> Assignee: Jeff Jirsa
> Labels: ponies
>
> As Cassandra clusters get bigger and bigger, and their topology becomes more
> complex, there is more and more need for a notion of "hub" and "spoke"
> datacenters.
> One of the big obstacles to supporting hundreds (or thousands) of remote dcs,
> is the assumption that all dcs need to talk to each other (and be connected
> all the time).
> This ticket is a vague placeholder with the goals of achieving:
> 1) better behavioral support for occasionally disconnected datacenters
> 2) explicit support for custom dc to dc routing. A simple approach would be
> an optional per-dc annotation of which other DCs that DC could gossip with.
