For this reason I invite you …

Percona Live 2014 behind; MySQL ahead
+0 Vote Up -0Vote Down

I started using MySQL 11 years ago.  That’s not too long compared to other people in the industry, but nonetheless here’s my perspective on the state of the MySQL industry after attending Percona Live MySQL Conference & Expo 2104.

In short, the attitude around MySQL has changed from “Does it work?” to “Is it fast and reliable?” to “How do we manage it?” To further generalize, these periods correspond roughly to the original MySQL AB team, Percona and Oracle, and the last period is the current period so key players are emerging, …

Your troubles are over, pt-heartbeat 2.1
+2 Vote Up -0Vote Down

Poor pt-heartbeat 2.1: it was perfectly fine through Percona Toolkit 2.1.7, but it’s had a rough life since. Its troubles are finally over as of Percona Toolkit 2.1.10. At a conference recently, a user joked to me that “Percona Toolkit is awesome, but you really broke pt-heartbeat.” It’s true, and if you haven’t heard or experienced the story, here it …

mk-query-digest uses less memory
+2 Vote Up -0Vote Down

Daniel changed mk-query-digest to use much less memory. It parsed and aggregated a 2GB MySQL slow query log file in a few dozen megabytes of memory for me yesterday. Thanks to Facebook for sponsoring this work.

How Maatkit benefits from test-driven development
+0 Vote Up -0Vote Down

Over in Maatkit-land, Daniel Nichter and I practice test-first programming, AKA test-driven development. That is, we write tests for each new feature or to catch regressions on each bug we fix. And — this is crucial — we write the tests before we write the code.* The tests should initially fail, which is a validation that the new code actually works and the tests actually verify this. If we don’t first write a failing testcase, then our code …

Download Maatkit

Maatkit version 2152 is ready for download. This release is also known as the “is this project really alive?” release. We thought we should delay until MySQL released a new Community Server version. Just kidding — it has nothing to do with that.

This release is also very significant in that it’s the first one that has large code contributions by someone other than myself. As you may …
