First blog post on my private blog for a while. This post discusses the FIT three-way tradeoff for distributed database system design. You can have two out of the three of: fairness, isolation, and throughput.

Daniel, it sounds like Upstart has a lot in common with private student loans.  The news has been full of stories about students taking out large loans, with unrealistic expectations about how a degree will affect their future earning potential.  Perhaps the long-term solution is better education for high school and college students about personal finances, and in the case of Upstart, the harsh realities of start-up life.

Your story also makes me worry that we are approaching another dot-com bubble.  However, it sounds like the investors, at least, have gotten a bit smarter this time around.

Dear Google,

You own Blogger. You own Google Plus. It would be really nice if you could integrate comment streams about the same blog post. Parallel threads are confusing and annoying to readers.

Posted this on Twitter last week, but forgot to put it on Google+ as well. I wrote up a detailed overview on the new Oracle NoSQL Database:

Gotta love the NoSQL guys (http://bradley-holt.com/2011/07/addressing-the-nosql-criticism/). They start off by saying "We make the full set of ACID guarantees". Then they start back-tracking. "We're only ACID compliant within a single data item --- transactions that span multiple data items are not ACID" ... "Oh yeah, and if you want the 'D' from ACID (durability) you to need to know enough to change a default parameter --- but we don't recommend it because things will go SLOW" ... "and even then, it's your responsibility to make sure your OS deals with fsync the way we want it to".

So, uh, then you don't really guarantee ACID, do you?

Five generations of database researchers (the guy to the left was the PhD advisor of the guy to the right). Database researchers are clearly getting shorter over time :)

Wow, it must become an invaluable photo in some years. Maybe the next generations. :)

The precomputation step is included in the benchmarking process. I.e., we are getting 500,000 tps including precomputation.

I finally got around to posting our upcoming VLDB paper on scalable Semantic Web data management up on my Website. I also blogged about it: http://dbmsmusings.blogspot.com/2011/07/hadoops-tremendous-inefficiency-on.html
