Thanks to SimonHF’s inputs, I have updated the 3n+1 benchmark specification to be clearer: http://docs.google.com/View?id=dd5f3337_12fzjpqbc2

Also, I modified the program to solve the improved benchmark and publish results: http://docs.google.com/Doc?docid=0AZN3e-tpxLwOZGQ1ZjMzMzdfMjJ2cnF2cWNnbQ&hl=en

On my laptop, with 8 concurrent processes accessing the database I get a fairly consistent update rate of between 30,000 and 40,000 updates/second (with journaling enabled for crash recovery) along with 145,000 to 172,000 reads/second with reads and updates happening in parallel.

I was also surprised at how high some of the numbers ranged – in computing the steps in the 3n+1 sequence for 1 through 1,000,000 the highest number encountered was 56,991,483,520.

Thanks folks for all your comments and feedback. A number of people have mentioned that there favorite database has not been included. Thing is, I am not really interested in building a comprehensive list – I wrote this post as a part of an exercise at Directi to understand the space and I thought it would be useful to share the research. IMHO there really is not much value in building a big list unless you spend a lot of time and energy to maintain it, since new products are constantly being built, and existing ones are constantly evolving (or dying out). Unfortunately I cannot spare that kind of time or energy. So if anyone is interested in taking over this content and build a wiki or something out of it, and keep it updated, I am most happy to contribute.

Very well written. I didn’t realize that cassandra uses zookeaper though. Is that a recent change ?

This is tasty — I’m surprised I haven’t seen it until now! Would like to see more details on HBase It’s good to have metrics to compare these “NoSQL” databases. Leads to structured discussion.

You may be interested in our new data platform at Drawn to Scale — we take a wider perspective than a single database. Our platform handles processing, storage, serving, and real-time querying and search. It’s easy, and scalable.

Sort of the “best of all worlds”. At least, we think so

Thought of turning this site into something in a wiki style so more information could be added?

I love this collection of information but I’d rather like to see it in a more structured format.
