> Remove StreamCoordinator.streamExecutor thread pool
> ---------------------------------------------------
>
> Key: CASSANDRA-14402
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14402
> Project: Cassandra
> Issue Type: Improvement
> Components: Streaming and Messaging
> Reporter: Jason Brown
> Assignee: Jason Brown
> Priority: Minor
> Fix For: 4.x
>
>
> {{StreamCoordinator.streamExecutor}} was previously introduced to initiate
> stream connections on a separate thread from the session invocation logic.
> With CASSANDRA-1229 streaming now uses non-blocking IO, and connection
> establishment is asynchronous via netty. Thus, the thread pool in
> {{StreamCoordinator}} is unneeded.
