Subject [jira] [Created] (CASSANDRA-14097) Per-node stream concurrency
Date Tue, 05 Dec 2017 20:23:00 GMT
Eric Evans created CASSANDRA-14097:
--------------------------------------

             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.
