MySQL on Windows: A survival guide for Linux-based DBAs

Why did we develop percona-agent in Go?

What Operating System do you run MySQL on in Production

This Friday we’ll have two polls instead of one to learn about Operating system we’re using to run MySQL. First Poll is about production use and second is about development. I know many developers would run MySQL on Linux in Production but use Windows or MacOS X for development. Please select operating system which actually […]

Percona XtraDB Cluster / Galera Tutorial at Percona Live NY 2012

I’ve mentioned this before, but I’m delivering a tutorial on Percona XtraDB Cluster / Galera at Percona Live NY 2012 right in midtown-Manhattan on October 1st.
