Aerospike guys were at a big data workshop at Bangalore last week. It's performance is pretty impressive. They claimed about >1M TPS with just 3 nodes and compared it with Couchdb which is claimed to achieve 1M TPS in 330 nodes. But unclear about their benchmarking method.
"But unclear about their benchmarking method". That can be said for every single performance claim they make. There's a rather distinct lack of objective facts.
