More-efficient cross-DC replication ----------------------------------- Key: CASSANDRA-1530 URL: https://issues.apache.org/jira/browse/CASSANDRA-1530 Project: Cassandra Issue Type: Improvement Components: Core Reporter: Jonathan Ellis Fix For: 0.7.1
Currently the coordinator node sends writes to each replica. In multi-dc situations, it would be more efficient to have the coordinator talk to a single node in each DC, which would forward the writes to the other replicas local to it. (All replicas would continue to ack to the coordinator.) Shouldn't be difficult to add a header to RMVH saying "consult the Strategy to see who else is local to you and queue it off to them as well." -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
