## Joining Booking.com

MySQL secondary November 14, 2014

I’m excited to be joining Booking.com at the Netherlands in a couple weeks 🙂

I’m looking forward to be working with a great team and friendly people! I hope to contribute from my experience and of course be challenged by difficult problems.

Booking.com is a supporter of open source in multiple aspects, and I am looking forward to continue working with open source solutions as well as releasing open source code.

I am leaving my work at Outbrain feeling grateful for the opportunity of working at this wonderful company! I am awed and humbled by the amazing teams I’ve worked with, whose level of knowledge and insights I can only aspire to match. Thank you in particular to the Infrastructure team, of which I was proud to be part of.

Outbrain allowed me and others (and in fact encouraged and supported) to develop as much open source as we saw fit. This is not a minor thing: when you orient your code towards open source, you need to make generalizations which are not always providing direct benefit to the company, and which consume precious time. I hold Outbrain in the highest respect for their support for open source.

It allows a /api/make-master call on such a slave (S), in which case it uses Pseudo GTID to enslave its siblings, and set S as read-only = 0. All we need to do is click the “Make master” button.
