VoltDB is out, benchmarks against Cassandra

This reads like marketing-blogspam to me. These two projects solve totally different problems, and the author acknowledges it, yet he still goes on to highlight benchmarks where VoltDB is 10-20x faster than Cassandra. Of course it's going to be! It's an in-memory store!<p>So why benchmark against Cassandra? It's got a lot of buzz around it, of course. What a better way to shove your name into the "NoSQL" ring. Blech.<p>With regard to the numbers themselves, I would refer the author to the CouchDB boys' discussion of benchmarks (under "Good Benchmarks are Non-Trivial"): <a href="http://books.couchdb.org/relax/reference/high-performance" rel="nofollow">http://books.couchdb.org/relax/reference/high-performance</a>

in memory vs not, will always have these kinds of results.<p>most people, most systems, aren't so hot about in memory datastores -- MySQL had MySQL-Cluster/NDB, and for lots of reasons it had trouble ever taking off.<p>For certain use cases, and definitely for benchmarking purposes, in memory datastores will always crush the competitors, but in the end, most people like reliable data storage.

I'm at Gluecon, where Mike Stonebraker (CTO of VoltDB) gave a talk about Volt this morning. He's very clear that VoltDB is not a NoSQL product; it's a SQL product, but a next-generation SQL product. He says they've achieved enormous performance gains by keeping ACID compliance by throwing out tons of older tech still present in MySQL and Oracle.

If he wanted something a bit closer to the voltdb model, why not go with mongo since your writes aren't immediately put to disk? It's more of a measure of how quickly you're shuttling data over the wire.<p>When you agree that it's apples to oranges, why continue?

This is cool, eventually we'll have every no-sql use case covered, so there exists a data store which conforms to your applications usage with respect to the CAP theorem...

code and configurations or it didn't happen

I see absolutely zero details about the actual configurations of either system. No replicability means it's just another opinion paper.

I wonder if this DB will be available from any clouds?
