Open Source DBA Ethos

I’m in Santa Clara at the Percona Live Conference and Expo.  I have been here less than 24 hours, but I have already had conversations with many fellow DBAs, some that I have met and worked with before, and others whom I am meeting for the first time.  It has been three years since my last visit, but being here shows you that as an Open Source DBA, you’re in sort of a “big family” of like minded, top notch, professionals.

I am proud to be an open source DBA because of our apparent values, values you see in almost everyone when you come to an event like this.

Who are we as Open Source DBAs ?

  • We are system experts.  Open source DBAs know their operating system.  They are not only focused on the database.
  • We are developers.  We contribute to source code within …
