The Clustrix story

After my recent post, the Clustrix guys raised their hands and briefed me. Takeaways included:

    Hi Curt,
    Thanks for taking the time for a quick briefing about Clustrix’s Clustered Database System.

    Overall you did a very good job capturing aspects of our solution. I recognize it was not much time, and we appreciate your attention.

    Here is clarification and/or additional information on a few of the points from your latest post about Clustrix:

    1) “Clustrix’s heart is in SQL…”

    • These are not separate options, since the heart of our system handles both in the same fashion. You get all the performance and scalability of key-value store without giving up full SQL relational and ACID transactional functionality.

    2) “Clustrix Sierra is fully parallel, with no “head” node…”

    • All nodes are peers, they all take reads and writes—and they are all seen as a single database.
    • Access to the cluster can be through our virtual IP address (VIP), an external load balancer, or directly to any one of the nodes. If our VIP is used, it will round-robin the connections to the cluster and will intelligently route around down nodes.

    3) “Clustrix is formed from the…”

    • Sergei and Paul met in August of 2006, joined forces and formally formed this company in October of 2006. They closed a major funding round December 2006. Prior to this, they had been exploring related, but separate companies.

    I hope that you find this helpful. We are happy to chat any time.

    Thanks, Dan! You did exactly what I want vendors to do after I post about them. 🙂

    As Yogi Berra would put it “Deja vu all over again”. Clustrix is merely Clustra Systems Redux. Even a quick scan of your report and the web site suggests the technology is amazingly similar to what we developed over 10 years ago. See I hope the market is kinder to Clustrix. The challenge is not technology but the market demand. We discovered that the vast majority (in excess of 95% is my “guesstimate”) of SQL database requirements can be met by bog standard RDBMS products. Very few need the kind of dynamic scalability and real-time repair that we delivered with the 5-9’s Clustra database. And now Oracle owns the code base for a production-quality, fault-tolerant, clustered SQL database. Interesting world. Timing is everything…

    Hi, I’ll go Clustra one better.

    Tandem Computers had distributed, ACID, transactional SQL in the eighties already, drawing on talent like Jim Gray, the late Turing Award winner out of UC Berkeley. SQL users on Tandem have benefitted from pushing distributed queries down to the data for over a quarter century now, which is why Tandem is used as a data warehousing machine although it was originally designed for massive, nonstop, fault-tolerant ACID online transaction processing.

    None of which detracts from the virtues of Clustra and Clustrix, however. I just wanted to provide some background, remembering my salad days when I thought the Rolling Stones were so incredibly brilliant simply because I was unaware of the great American Blues tradition they drew from.

    […] Clustrix says it has a few production users, some big-name, but is not disclosing them yet. […]

    Tandem’s SQL product is now sold by Hewlett Packard. It is called NonStop SQL/MX and runs on HP’s proprietary NonStop servers. HP acquired this via its acquisition of Compaq. The only differences I see between SQL/MX and Clustrix is the use of MVCC for concurrency and the machine level code in query plan fragments.
    HP’s product page for SQL/MX is here:
