New England Database Summit (January 28, 2010)
New England Database Day has now, in its third year, become a “Summit.” It’s a nice event, providing an opportunity for academics and business folks to mingle. The organizers are basically the local branch of the Mike Stonebraker research tree, with this year’s programming head being Daniel Abadi. It will be on Thursday, January 28, 2010, once again in the Stata Center at MIT. It would be reasonable to park in the venerable 4/5 Cambridge Center parking lot, especially if you’d like to eat at Legal Seafood afterwards.
So far there are two confirmed speakers — Raghu Ramakrishnan of Yahoo and me. My talk title will be something like “Database and analytic technology: The state of the union”, with all wordplay intended.
There’s more information at the official New England Database Summit website. There’s also a post with similar information on Daniel Abadi’s DBMS Musings blog.
Edit after the event:

Comments on a fabricated press release quote
My clients at Kickfire put out a press release last week quoting me as saying things I neither said nor believe. The press release is about a “Queen For A Day” kind of contest announced way back in April, in which users were invited to submit stories of their data warehouse problems, with the biggest sob stories winning free Kickfire appliances. The fabricated “quote” reads: Read more

Boston Big Data Summit keynote outline
Last month, Bob Zurek asked me to give a talk on “Big Data”, where “big” is anything from a few terabytes on up, then moderate a panel on cloud computing. We agreed that I could talk just from notes, without slides. So, since I have them typed up, I’m posting them below.
Calpont’s InfiniDB
Since its inception, Calpont has gone through multiple management teams, strategies, and investor groups. What it hadn’t done, ever, is actually shipped a product. Last week, however, Calpont introduced a free/open source DBMS, InfiniDB, with technical details somewhat reminiscent of what Calpont was promising last April. Highlights include:
- Like Infobright, Calpont’s InfiniDB is a columnar DBMS consisting of a MySQL front end and a columnar storage engine.
- Community edition InfiniDB runs on a single server.
- One of commercial/enterprise edition InfiniDB’s main claims to fame will be MPP support.
- There’s no announced time frame for commercial edition InfiniDB.
- InfiniDB’s current compression story is dictionary/token only, with decompression occurring before joins are executed. Improvement is a roadmap item.
- Indeed, InfiniDB has many roadmap items, a few of which can be found here. Also, a great overview of InfiniDB’s current state and roadmap can be found in this MySQL Performance Blog thread. (And follow the links there to find performance discussions of other free analytic DBMS.)
- One thing InfiniDB already has that is still a roadmap item for Infobright is the ability to run a query across multiple cores at once.
- One thing free InfiniDB has that Infobright only offers in its Enterprise Edition is ACID-compliant Insert/Update/Delete. (Note: I wish people would stop saying that Infobright Enterprise Edition isn’t ACID-compliant, since that point was cleared up a while ago.)
- InfiniDB has no indexes or materialized views.
- However, InfiniDB’s retrieval is expedited by something called “Extents,” which sounds a lot like Netezza’s zone maps.
Being on vacation, I’ll stop there for now. (If it weren’t for Tropical Storm/ depression Ida, I might not even be posting this much until I get back.)
