Another video from the recent OpenSQLCamp in Portland, Oregon….Earlier today I uploaded the Lightning Talk Videos. Due to the holiday I am unsure when the rest of the videos will be ready. When they are, I will do one blog post featuring them all.
However, I have had several requests for this specific video, so here is Brian Aker speaking about Drizzle.
The slides are up at http://www.slideshare.net/brianaker/drizzle-opensql-camp, and here’s the video:

All the videos have been processed, and I am working on uploading them to YouTube and filling in details for the video descriptions. Not all the videos are up right now….right now all the lightning talks are up.
I am working on uploading the rest of the sessions, so look for them next week, though I may have one or two up very soon.

For the past two months, I have been running tests on TokuDB in my free time. TokuDB is a storage engine put out by Tokutek. TokuDB uses fractal tree indexes instead of B-tree indexes to improve performance, which is dramatically noticeable when dealing with large tables (over 100 million rows).
For those that like the information “above the fold”, here is a table with results from a test comparing InnoDB and TokuDB. All the steps are explained in the post below, if you want more details, but here’s the table:
