-------------------------------------------
Summary: Verify effect of CASSANDRA-14252 on streaming endpoint
selection
Key: CASSANDRA-14555
URL: https://issues.apache.org/jira/browse/CASSANDRA-14555
Project: Cassandra
Issue Type: Task
Components: Streaming and Messaging
Reporter: Sam Tunnicliffe
Fix For: 4.x
CASSANDRA-14252 makes a slight change to {{DynamicEndpointSnitch}} so that it
is somewhat more likely a replica in a remote DC is contacted when replicas in
the local DC are considered degraded. This seems reasonable on the read path,
but it could also affect selection of endpoints for streaming and cross DC
streaming is probably something that operators want to control more tightly. To
be clear, I’m not 100% sure that this is actually an issue, but I’d like to
have some investigation into it before we ship a change to default behaviour.
