OpenSQLCamp Lightning Talk Videos

OpenSQLCamp was a huge success! Not many folks have blogged about what they learned there….if you missed it, all is not lost. We did take videos of most of the sessions. All the videos have been processed, and I am working on uploading them to YouTube and filling in details for the video descriptions.

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.

So what’s the solution? Well, there are ways to deal with it.

Video: Building a MySQL Slave and Keeping it in Sync

Last night at the Boston MySQL User Group I presented on how to get a consistent snapshot to build a slave, use mk-table-checksum to check for differences between masters and slaves on an ongoing basis, and how to use tools such as mk-table-sync and mysqldump to sync the data if there are any discrepancies. The links to the slides and video are here.
