--------------------------------------------------------------------
Pushed update to: https://github.com/yukim/cassandra/commits/5286-2
Doc is updated too: https://gist.github.com/yukim/5672508
Changes:
* API revised. Basically, you build your [stream
plan|https://github.com/yukim/cassandra/blob/5286-2/src/java/org/apache/cassandra/streaming/StreamPlan.java],
execute it, and get [future result of the
streaming|https://github.com/yukim/cassandra/blob/5286-2/src/java/org/apache/cassandra/streaming/StreamResultFuture.java].
* Migrated all stream operation to new API including nodetool. Bulkloader is
not working because of CASSANDRA-5542 though. Repair works with new API, but we
should refactor after CASSANDRA-5426.
* Versioned streaming protocol
Still not implemented(but things we can do in separate tickets IMHO):
* JMX notification
* Stream different version of SSTable
* Progress updated by row on read path

> Streaming 2.0
> -------------
>
> Key: CASSANDRA-5286
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5286
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Yuki Morishita
> Labels: streaming
> Fix For: 2.0
>
>
> 2.0 is the good time to redesign streaming API including protocol to make
> streaming more performant and reliable.
> Design goals that come up in my mind:
> *Better performance*
> - Protocol optimization
> - Stream multiple files in parallel (CASSANDRA-4663)
> - Persistent connection (CASSANDRA-4660)
> *Better control*
> - Cleaner API for error handling
> - Integrate both IN/OUT streams into one session, so the
> components(bootstrap, move, bulkload, repair...) that use streaming can
> manage them easily.
> *Better reporting*
> - Better logging/tracing
> - More metrics
> - Progress reporting API for external client
