Blake Eggleston updated CASSANDRA-14115:
----------------------------------------
         Reviewer: Jason Brown
    Fix Version/s: 4.0
           Status: Patch Available  (was: Open)

I have a first pass of this ready for review 
[here|https://github.com/bdeggleston/cassandra/tree/14115-v1].

This abstracts the storage layer exposed to streaming behind 4 interfaces:
* 
[TableStreamManager|https://github.com/bdeggleston/cassandra/blob/14115-v1/src/java/org/apache/cassandra/streaming/TableStreamManager.java]
* 
[StreamReceiver|https://github.com/bdeggleston/cassandra/blob/14115-v1/src/java/org/apache/cassandra/streaming/StreamReceiver.java]
* 
[OutgoingStream|https://github.com/bdeggleston/cassandra/blob/14115-v1/src/java/org/apache/cassandra/streaming/OutgoingStream.java]
* 
[IncomingStream|https://github.com/bdeggleston/cassandra/blob/14115-v1/src/java/org/apache/cassandra/streaming/OutgoingStream.java]

The javadocs on each interface explains how they work, and the implementations 
for the current storage layer are in {{o.a.c.db.streaming}}. That's probably 
not where they'll be or what they'll be named at the end of this project, but 
there's plenty of time for bikeshedding about that :)
