> Verify effect of CASSANDRA-14252 on streaming endpoint selection

>
> 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.
