695k TPS with Node.js and VoltDB

I'd like to add an independent voice too. I tried VoltDB out around a year ago. Ran it on 3 servers, with k=1 (all data replicated on 2 nodes). Servers were Dell PowerEdge 860 - only 8GB RAM, and a Q6600 quad-core processor. They cost maybe $500 or so. Even with a low-end buildout, I was able to hit around 110k TPS. This wasn't one of VoltDB's sample apps; it was a small proof-of-concept for a telecom application. They don't seem to be riding the hype train.

As far as open source: I was using the .NET client, and fixed a few issues with it. The folks at VoltDB were really responsive about working with me and accepting my patches. They also took time to explain the inner workings, sorta give me a launching point to investigating the core code. Pretty good experience for a commercial open source project.

Yes, very basic realtime billing/CDR storage. With traditional DBs, I have to resort to batching balance: Read N messages from queue, compute overall balance updates, then apply at once. With VoltDB, I can just fire off records as they come in.
