--------------------------------------
Summary: Per-node stream concurrency
Key: CASSANDRA-14097
URL: https://issues.apache.org/jira/browse/CASSANDRA-14097
Project: Cassandra
Issue Type: Bug
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.
