Database auditing alternatives for MySQL

Database auditing is the monitoring of selected actions of database users. It doesn’t protect the database in case privileges are set incorrectly, but it can help the administrator detect mistakes. Audits are needed for security. You can track data access and be alerted to suspicious activity. Audits are required for data integrity. They are the […]

The new Percona Server 5.5.37-35.0 and Percona Server 5.6.17-65.0-56, announced yesterday (May 6), both include the open source version of the MySQL Audit Plugin. The MySQL Audit Plugin is used to log all queries or connections (“audit” MySQL usage). Until yesterday’s release, the MySQL Audit Plugin was only available in MySQL Enterprise. EDIT:  Just to be clear, this implementation […]

10 years of MySQL User Conferences

In preparing for this month’s Percona Live MySQL Conference and Expo, I’ve been reminiscing about the annual MySQL User Conference’s history – the 9 times it previously took place in its various reincarnations – and there are a lot of good things, fun things to remember. 2003 was the year that marked the first MySQL user conference […]

mysql-proxy, urgh performance and scalability ?

For one our project I needed proxy solution, and mysql-proxy is one of well-known, so it was logical first choice. The obvious question which come in mind is what performance penalty we have using mysql-proxy, version 0.7.1. So it is easy to test. (By the way sysbench recently was pushed to Launchpad, see lp:sysbench, and […]

How Percona does a MySQL Performance Audit

Our customers or prospective customers often ask us how we do a performance audit (it’s our most popular service). I thought I should write a blog post that will both answer their question, so I can just reply “read all about it at this URL” and share our methodology with readers a little bit. This […]

New MySQL Community release – Great job MySQL !

Wow!. New MySQL Community release – MySQL 5.0.67 is just out which as manual says first community release since 5.0.51b. I just recently complained about community release irregularity and I’m glad to see the new release after all. I only hope this will not be one time event but MySQL will follow its own promises […]

Should we proclaim MySQL Community Edition Dead ?

We were chatting with Jeremy Cole today and he brought to my attention last version of MySQL Community Eddition (5.0.51) was released in November 2007 – over 7 months ago. MySQL 5.0.51a and MySQL 5.0.51b security fixes were released but these can’t be considered proper releases. If we look at the old Kaj’s Announcement we […]

CentOS Comes with free build of MySQL Enterprise ?

As I already wrote you can well go to Linux distribution vendors if you’re looking for recent MySQL version in a hassle free binary form. (On the time of this writing you could only get binaries for MySQL Community 5.0.45 from MySQL Download Pages which was released in July and so about half a year […]

MySQL Quality of old and new features

Recent couple of days our team was pointed to number of bugs in MySQL 5.0 which again seriously shakes the confidence in both MySQL Quality Control and bug fix promptness. Let me just take couple of bugs as examples: Triggers broken with auto-increment columns for Innodb tables (bug 26316). As you can see this bug […]

MySQL Community contrubutions

I’ve just read post http://www.planetmysql.org/kaj/?p=123 about MySQL plans of including community contributions into releases. I understand MySQL’s interest to make releases stable, and includes contributions only into development tree, but this is not something I would like to see. Look, MySQL 5.0 was shipped as production on 19 October 2005. Since almost 2 years there […]
