About me…

Hi. Thank you for taking the time to read my scribblings… I am Rob Klopp… a somewhat schizophrenic data warehouse expert with at least two personalities (my friends might chronicle more).

First… I am a geekish individual contributor who understands technology deeply. I stay very current from this perspective and act as a CTO or a CPO (Chief Product Officer). Then, to get things done, I take on executive management roles. For example, I was a Presidential appointee and the CIO at the U.S. Social Security Administration. I am very fortunate to be able to work in either role.

I currently work:

  • for the Greenplum Division of EMC
  • with the HANA group at SAP
  • as an Independent Consultant
  • as the CIO of the US Social Security Administration
  • as an Independent Consultant

I started in the data warehouse space in 1987 at Teradata. My LinkedIn profile is here… feel free to connect.

I started this blog to try to sort out marketing fluff from the architectural trade-offs each product makes. In the end any product’s price and performance is the result of those choices and of the state of their feature set. These topics are composed by my geekier self. Soon enough, and with the forbearance of my readers, I will let my executive side muse out and compose some thoughts on the state of the market…

Let me end this as I started by thanking folks for reading this… I am surprised by the response for sure…

  1. Hi Rob,

    I have recently come across this blog and cannot express in words how much I enjoy your frank and illuminating evaluations of the latest data warehouse developments, along with the informative debate that usually ensues.

    One question: why did you leave EMC for SAP?



    1. Thank you for the kind words, Andrew…

      Why did I leave EMC… concern over the business strategy of the Greenplum Division…. You can see some of this in my post about Hadoop eating Greenplum and will see a little more in my upcoming 2 cents on Greenplum.

      In addition they were very much uninterested in hearing my opinion on these subjects… To be fair Greenplum is in good company on this point joining my parents, my ex-wife, and several Facebook friends.

      Why SAP… as part of gathering competitive intelligence for Greenplum I became convinced that SAP was doing the right things with HANA.



  2. Wow. Terrific blog, which in five minutes of reading has already saved me from a possible strategic blunder (based on your comments about Greenplum performance, mostly). Back to the drawing board. Too bad you’re not in the Bay Area– I’d buy you a number of beers while I picked your brain…


  3. Attending your presentation in the Altmeyer. I asked the first question.
    I think your ideas are fresh and exciting. Truly hoping SSA can move forward with you.
