-----------------------------------------
Summary: 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: Core
Reporter: Tupshin Harper
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.
