/**
* Non-blocking streaming with netty
* This document describes the implementation details of the streaming protocol. A listener for a streaming
* session listens on the same socket as internode messaging, and participates in the same handshake protocol
* That protocol is described in the package-level documentation for {@link org.apache.cassandra.net.async}, and
* thus not here.
*
* Streaming 2.0 was implemented as CASSANDRA-5286. Streaming 2.0 used (the equivalent of) a single thread and
* a single socket to transfer sstables sequentially to a peer (either as part of a repair, bootstrap, and so on).
* Part of the motivation for switching to netty and a non-blocking model as to enable stream transfers to occur
* in parallel for a given session.
*
* Thus, a more detailed approach is required for stream session management.
*
* Session setup and management
*
* The full details of the session lifecycle are documented in {@link org.apache.cassandra.streaming.StreamSession}.
