...you're traveling on family holiday, and each time you wish to suggest you should check up on the tourist information center, you repeatedly come up with: "Let's ask at the INFORMATION_SCHEMA and see what we can get".

Also, doing so while wearing an OpenSQL Camp T-shirt doesn't help.

  • The fact that people are still arguing on how “MySQL” should be pronounced.
4 ways that instrumentation is like sex
+2 Vote Up -0Vote Down

In an application such as a database server, instrumentation is like sex: it’s not enough to know how often things happen. You also care about how long they took, and in many cases you want to know how big they were.

“Things” are the things you want to optimize. Want to optimize queries? Then you need to know what activities that query causes to happen. Most systems have at least some of this kind of instrumentation. If you look around at… let’s not pick on the usual targets… oh, say Sphinx, Redis, and memcached. What metrics do they provide? They provide counters that say how often various things happened. (Most of these systems …
