MySQL Conference - Two Interesting Items

Two interesting presentations from this years' MySQL Conference

 - Capacity Planning for LAMP - John Allspaw the Engineering Manager at flickr talks about how they use Ganglia (pdf).

My favorite excerpt:


Accept the observer effect

 * measurement is a necessity

 * it's not optional

- Wikipedia: Site Internals, Configuration and Code Examples, and Management Issues - Domas Mituzas (MySQL and Wikimedia) talks about the internals of scaling a large site like Wikipedia (pdf). There is a good section on caching with memcached, although it applies to caching in general.
