-----------------------------------------
Summary: Streaming 2.0
Key: CASSANDRA-5286
URL: https://issues.apache.org/jira/browse/CASSANDRA-5286
Project: Cassandra
Issue Type: Improvement
Reporter: Yuki Morishita
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
