Subject [jira] [Commented] (CASSANDRA-13580) Readonly datacenter support
Date Thu, 08 Jun 2017 14:33:18 GMT


Marcus Eriksson commented on CASSANDRA-13580:

bq. Nodes in a read only DC will still receive and persist data from the rest of the clusters
and get counted against the CL, right?
good point, this wont work the way it is implemented now, and I doubt the use case is common
enough to warrant a more complicated solution.

> Some setups include datacenters where only reads are performed (example could be datacenter
dedicated for taking backups).
> We could use this information during repair to make sure that we never stream out of
a read only dc.
