----------------------------------------
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.
