Move streams data to too many nodes. ------------------------------------ Key: CASSANDRA-3041 URL: https://issues.apache.org/jira/browse/CASSANDRA-3041 Project: Cassandra Issue Type: Improvement Components: Core Affects Versions: 0.8.4, 0.7.8 Reporter: Nick Bailey Fix For: 1.0
When you decommission a node, it only streams data to the node that is just now gaining responsibility for the node's primary range. When you move a node it streams data to every node that is responsible for the node's primary range. This is way more than it needs to, and could be bad in multi-dc setups. We should absolutely use this bug as a chance/reason to better unify that code, since move should be doing the same thing decom does. This might be worth backporting to 0.8 as well. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
