Reflections on return to MySQL Community and Ecosystem
+1 Vote Up -0Vote Down

After a four year hiatus, my participation in last week’s Percona Live MySQL Users conference marked my official return to the MySQL Community and Ecosystem. As with earlier renditions this year’s “UC” was very well attended with a healthy mix of familiar faces and new blood, all coming together to discuss, present and explore the boundaries of the most popular and widely used open source database on the planet.  There were many good, informative keynote and technical sessions, BoFs and the exhibit hall was packed most of the operating hours with those …

A real fast list of stuff from the Percona Live 2014 event.

Yahoo’s Performance Analyzer

Yahoo is developing a MySQL performance analyzer that should be released as open source later this year. From the demo, it looks like it pulls in most of the MySQL metrics, shows you a processlist and then lets you drill into a processlist with explain. Will have to keep my eye out for this.

How to convert master-slave to master-master replication in MySQL
+0 Vote Up -0Vote Down

Recently, I have worked on one of this case where customer wanted to convert master-slave to master-master replication. They wanted to write on one master and keep another master as a hotspare. Many people are using this kind of environment with MySQL replication.

I would like to explain here in very simple steps that how we can do that. You can also follow the same steps if you want to promote only slave as a master in master-slave replication. Sometimes, this process will be helpful if you have master-slave replication and you want to rebuild or upgrade both the servers one by one. In that case, you have to shift traffic from one server to the other, take down …

Capturing MySQL Data with tcpdump
+0 Vote Up -0Vote Down
