As part of the prep for my keynote on Wednesday at the MySQL User Conference, I decided to ask some of my Web 2.0 friends just how they were using databases in their applications. Over the next couple of days, I'm going to post what I heard back. I'm not going to draw any conclusions till the end of the series, but just let people speak for themselves.

In this first installment, a few thoughts from Cory Ondrejka and Ian Wilkes of Linden Labs, creators of Second Life. Cory wrote:

Your timing is, of course, perfect because we're a) in the midst of converting much of our backend architecture away from custom C++/messaging and into web services and b) we spent yesterday afternoon fighting some database cliff that we just hit. Since I'm about to get on a redeye, let me introduce you to Ian Wilkes, our Director …

Argh! MySQL cluster currently stores in RAM only. That means if I have 100 machines each with 4 gigabytes of RAM, then I can store 200 gigabytes of data! Hurrah! That's at least what I learnt in the tutorial, feel free to correct me if I am wrong.

So, there are two access points with the ESSID "MySQL-Hyatt" that I can see from my coffee drinking spot here in the foyer. iwlist tells me that they have encryption off, which matches what the conference handbook says should be the case. No DHCP leases are being offered though. I guess that means that the conference network hasn't been commissioned yet. Oh well.

Update: Oh, it works in the conference rooms, which have a different ESSID.

I'm working on a Visual Studio package for MySQL and discovering that it is possible to write hundreds of pages of documentation and still not be able to answer some of the most basic questions.  Microsoft does it over and over again. 

In this case I'm using managed code to create a custom editor for our database objects (think Server Explorer).  I don't want to register a file extension.  After considerable trial and error, I got  a chunk of code working.  This code called IVsUIShellOpenDocument.InitializeEditorInstance and IVsUIShell.CreateDocumentWindow and my editor appeared.  However, it would not prompt to save when the window pane was closed.  GetDocumentInfo showed an edit lock on my document but UnlockDocument could not remove it.

I replaced this code with simpler code that called IVsUIShellOpenDocument.OpenSpecificEditor and my documents suddenly started prompting to save …

MySQL Users Conference 2006 - MySQL Cluster: New Features and Enhancements

If you are coming to my talk, make sure you know a bit about cluster beforehand. Being at Johan’s talk today was a good idea.

Or reading the manual chapter.

Otherwise you may end up being quite lost for a lot of the talk. Mine isn’t an intro to cluster one.

Up at 5:50am, dressed by 6:30am, and leaving the house by 7:10am to get on the VTA light rail by 7:30am. All because the tutorials start at 8:30am, and I want to catch the train instead of using up fuel...
