> 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
