Cluster Study Guide, Edition 2

My new edition of the MySQL 5.1 Cluster DBA Certification Study Guide arrived today. It features a bigger format, corrections, and much better graphics. And it is $10 less expensive.

The MySQL Cluster is just different enough from the 'old fashioned' server to be confusing to long time MySQL DBAs. This book points out common problems people have getting their clusters configured. So if you are curious about how clusters work and want more than the man pages as a reference, order you copy today!

EXPLAIN Cheatsheet

At the 2008 MySQL Conference and Expo, The Pythian Group gave away EXPLAIN cheatsheets. They were very nice, printed in full color and laminated to ensure you can spill your coffee* on it and it will survive.

For those not at the conference, or those that want to make more, the file is downloadable as a 136Kb PDF at explain-diagram.pdf

* or tea, for those of us in the civilized world.

  • Speaker: Mikael Ronstrom, PhD, the creator of the Cluster engine
  • Explains the cluster structure
  • Aspects of performance
    • Response times
    • Throughput
    • Low variation of response times
  • Improving performance
    • use low level API (NDB API), expensive, hard
    • use new features in MySQL Cluster Carrier Grade Edition 6.3 (currently 6.3.13), more on this later
    • proper partitioning of tables, minimize communication

Setting Up A MySQL Cluster

This article contains my notes and detailed instructions on setting up a MySQL cluster. After reading it, you should have a good understanding of what a MySQL cluster is capable of, how and why it works, and how to set one of these bad boys up. Note that I'm primarily a developer, with an interest in systems administration but I think that every developer should be able to understand and set up a MySQL cluster, at least to make the dev environment more robust.

Notes

In short, a MySQL cluster allows a user to set up a MySQL database shared between a number of machines. Here are some benefits:
  • High availability. If one or some of the machines go down, the cluster will stay up, as long as there is at least one copy of all data still present. The more redundant copies of data there are, the more machines you can afford to lose.
  • Scalability. Distributed architecture allows for load balancing. If your MySQL …

MySQL Conference 2008

April 14-17th is going to be an exciting time. Why? Because the 2008 MySQL Conference and Expo is going to be held in Santa Clara, CA. Who would want to miss out on a chance to lurk around, let alone talk to, some of the smartest people in the MySQL world? Well, those who don't have at least $1000+, of course. A 3 day pass to the conference without tutorials costs a whopping $1199. A full pass would dry up your pockets $1499.

Well, "good news everyone". Thanks to Sheeri Cabral of The Pythian Group, PlanetMySQL.org, Jeremy, and, …
