welcome to the party, IBM
IBM has finally realized developers are let down by 10gen's NoSQL implementation, and IBM can provide an enterprise solution to address 10gen's failings. This API needs standardization - but make no mistake, this is IBM's move to cannibalize 10gen's enterprise sales effort by offering DB/2.
At Aerospike, we've delivered a fast and scalable ACID NoSQL solution, and seen huge market uptake - we understand IBM's interest in playing catch up in this market.
The fact that Aerospike has several ex-DB/2 engineers and advice from Don Haderle has helped.
