Notes and comments — October 31, 2012

Time for another catch-all post. First and saddest — one of the earliest great commenters on this blog, and a beloved figure in the Boston-area database community, was Dan Weinreb, whom I had known since some Symbolics briefings in the early 1980s. He passed away recently, much much much too young. Looking back for a couple of examples — even if you’ve never heard of him before, I see that Dan ‘s 2009 comment on Tokutek is still interesting today, and so is a post on his own blog disagreeing with some of my choices in terminology.

Otherwise, in no particular order:

1. Chris Bird is learning MongoDB. As is common for Chris, his comments are both amusing and enlightening.

2. When I relayed Cloudera’s comments on Hadoop adoption, I left out a couple of categories. One Cloudera called “mobile”; when I probed, that was about HBase, with an example being messaging apps.

The other was “phone home” — i.e., the ingest of machine-generated data from a lot of different devices. This is something that’s obviously been coming for several years — but I’m increasingly getting the sense that it’s actually arrived.

3. Todd Papaioannou added a comment summarizing the Continuuity story.

4. Stay tuned for more on Cloudera Impala. (Edit: Now posted.)

5. I never seem to get around to blogging about Master Data Management (MDM), in part because Informatica never rescheduled a briefing with me that they canceled in July. But it’s an important concept to recognize, at least to the extent:

Every time you build an application — NoSQL or otherwise — that stores data redundantly with other applications over other data stores, you’re making your MDM problem bigger.

6. Metamarkets’ Druid was open-sourced. Numerous other product introductions and so on that I’ve hinted at have happened as well.

7. In a comment on my Platfora post, Neil Hepburn made a good point about associative UIs and acyclic join paths.

8. I made a hash of my attempted glossary entry for DBMS, and need to rethink it.

9. IBM’s DataStage is based on Pick technology. That makes sense based on Ascential’s company history; even so, it was news to me.

    I am quite sad to hear about Dan Weinreb’s passing away. I had a chance to work with him during the early 90’s when both of us were at Object Design (with Tom Atwood and co.). He was one of the founders at ODI.

    I learnt quite a few design concepts from Dan during our discussions. More recently (in 2009), I tried to get him to work on Informatica related technologies, but without luck.

    I hope his family members are well, and may his soul rest in peace!

    Regards,
    Sanjeev Kumar.

  2. Some trends that will continue in 2013 | DBMS 2 : DataBase Management System Services on December 18th, 2012 9:43 pm

    [...] Growing attention to machine-generated data. Human-generated data grows at the rate business activity does, plus 0-25%. Machine-generated data grows at the rate of Moore’s Law, also plus 0-25%, which is a much higher total. In particular, the use of remote machine-generated data is becoming increasingly real. [...]
