why would i use voltdb? serious question. this is the first time i hear about voltdb.

i mean, i can use a postgres or mssql cluster for SQL needs and/or i can use riak/... for kv and/or cassandra/... for column indexed storage and/or ... etc. why should i look at voltdb?

Well, one thing we can say definitively today is that VoltDB offers strong serializability, when almost no other clustered systems do, and when they do, they are slow.

But my more typical answer is the combination of throughput and transactional logic. No other system does both as well as VoltDB. This comes up a lot in policy enforcement, fraud detection, online gaming, ad-tech, billing-support and more.

Here are some blog posts that might help:
