SG, can you please add any requirements that you may have in mind to the JIRA.

I didn't add Redis spout (using pubsub or list) because it can't meet at-least-once semantic. Do you have any sketches or design doc for Cassandra spout?

But I could not find any such thing documented at: http://storm.apache.org/releases/1.0.3/storm-cassandra.html Is there a reason why there exists only Cassandra Bolt? Would Cassandra Spout be a welcome addition to the codebase? Thanks SG
