Cliff Gilmore created CASSANDRA-7584: ----------------------------------------
Summary: SSTableLoder Multi-DC Improvment Key: CASSANDRA-7584 URL: https://issues.apache.org/jira/browse/CASSANDRA-7584 Project: Cassandra Issue Type: Improvement Components: Tools Reporter: Cliff Gilmore Right now SSTableLoader requires connectivity to the entire cluster to stream data. This becomes a problem when the cluster grows to be more than a single datacenter. The primary concern is that many replicas will be sent across the WAN resulting in a much larger network burden than would be ideal. Also, allowing SSTableLoader to reach across the networks can be a security burden on the implementation. A possible solution to this situation is to have the local datacenter nodes do a streaming relay of a single replica out to each additional datacenter where it is then relayed internally as appropriate. -- This message was sent by Atlassian JIRA (v6.2#6252)
