A Smattering of Percona Live 2014 Stuff

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.

ChatOps with Hubot

GitHub’s Sam Lambert has a set of hubot chatops scripts for MySQL. I was already looking at depoying hubot for the ability to push messages from a remote source into an IRC channel, so this would be a natural fit. He also mentioned using Janky to tie CI with hubot.

Percona Live MySQL Conference and Expo 2014: Things I’m looking forward to

The Percona Live MySQL Conference and Expo 2014 is just two months away. I’m very excited about this year’s event which continues our tradition of open technical discussions and inviting all parties to the table.

We have a great amount of technical talks from Oracle – I’m especially excited about future-focused talks shedding some light about what to expect in MySQL 5.7 and beyond. This content is best covered by developers actually designing the system and writing the code. We also have great coverage of MySQL alternatives from Percona and MariaDB. You can view the entire program here.

It is great to see well-rounded coverage of many …

Why software patents are evil

Mark Cuban is no fool. A tech billionaire, the no-nonsense owner of the Dallas Mavericks is just the sort of person you'd expect to value software patents. So the title of his blog post this Tuesday, "I hope Yahoo crushes Facebook in its patent suit," may not look out of place to you.

A Glance at MySQL MHA

Yoshinori Matsunobu sparked some interest recently when he posted about his MySQL MHA HA solution, and there has been some discussion of it internally at Yahoo compared with the standard we currently have.  

Full disclosure:  I haven’t read every bit of the documentation or tried it out yet, so I apologize in advance to Yoshinori if I mistakenly represent his hard work. 

I see a lot of great ideas in Yoshinori’s release, it seems to focus on two main problems:

  1. A process to monitor an active master and perform a failover when it fails
  2. The bit that finds the most “caught-up” slave and distributes …
