Yes. Actually we [cassandra] are seeing a fair number of people switching to Cassandra from hbase because of speed and reliability (no single points of failure).
I just looked at couchdb-lounge because I'm very interested in partitioning and hadn't heard about it.
The wiki unfortunately left the important questions unanswered. Does lounge handle the rebalancing when new shards are added/removed? Do I have to take the cluster offline to add new nodes? What are the failure modes (e.g. a node failing and coming back)? How is a replacement node bootstrapped?
Since none of that is mentioned I have my doubts that lounge is handling it adequately. But I'd be glad to hear otherwise!
