		<description><![CDATA[In October 2008, Baron posted How to Check MySQL Replication Integrity Continually. Here at Pythian we have developed a method based on that post, and added &#8220;verifying that masters and slaves are in sync&#8221; to our standard battery of tests. We call it &#8220;Continual replication sync checking&#8221;. This article will explain how it works, how [...]]]></description>

		<description><![CDATA[Last week I had to confront one of those situations where you can&#8217;t really tell what is going on with a piece of software, and the final conclusion would sound completely crazy if postulated as the initial hypothesis. The regular MySQL commands and utilities fall short in these cases, so I had to resort to [...]]]></description>

		<description><![CDATA[Over the weekend, I worked on a client&#8217;s two computers, trying to get a slave in sync with the master. It was during this time that I began thinking about: a) how this never should have happened in the first place. b) how &#8220;slave drift&#8221; could be kept from happening. c) how this is probably [...]]]></description>

		<description><![CDATA[Scenario: Someone wants to know which of the over 50 MySQL users have certain privileges. There are many ways to solve this problem. Some of these scenarios are tedious and repetitious, others take no time at all. The issue, of course, lies in what the &#8220;certain&#8221; privileges are. If it is &#8220;who has the SUPER [...]]]></description>

		<description><![CDATA[The Maatkit toolkit is a real blessing for the MySQL DBA. And while its documentation is pretty good, in some cases it&#8217;s necessary to read carefully a second and third time to make sure you are not missing an important piece of information. In this article I will comment on mk-table-chksum and mk-table-sync. My comments [...]]]></description>

My mission is to figure out (cold) some of the characteristics of the queries being run, and particularly if they&#8217;re &#8220;good&#8221; or &#8220;bad&#8221;. In my arsenal of &#8220;tools I really want to check out&#8221; has been Maatkit&#8216;s Query Profiler. They&#8217;re very different tools. Maatkit&#8217;s query profiler [...]]]></description>
