Eric Evans updated CASSANDRA-14097:
-----------------------------------
Component/s: Streaming and Messaging
> Per-node stream concurrency
> ---------------------------
>
> Key: CASSANDRA-14097
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14097
> Project: Cassandra
> Issue Type: Improvement
> Components: Streaming and Messaging
> Reporter: Eric Evans
>
> Stream sessions with a remote are bound to a single thread, and when
> compression is in use this thread can be CPU bound, limiting throughput
> considerably. When the number of nodes is small (i.e. when the number of
> concurrent sessions is also low), rebuilds or bootstrap operations can take a
> very long time.
> Ideally, data could be streamed from any given remote concurrently.
