Description

This short talk will be about an incident that kept DBAs working on a weekend. Two bugs, one in our application code and one in the database, joined force and almost brought down Booking.com.

Jean-François Gagné

Senior System Engineer, Booking.com

Biography:

Since joining Booking.com in October 2013, Jean-François is working on growing the MySQL/MariaDB installations by removing replication bottlenecks (he also works on other engineering problems that are less relevant here). Some of his latest projects are making Parallel Replication run faster and deploying Binlog Servers. He also has a good understanding of replication in general and a respectable understanding of InnoDB, Linux and TCP/IP. Before Booking.com, he worked as a System/Network/Storage Administrator in a Linux/VMWare environment, as an Architect for a Mobile Services Provider, and as a C and Java Programmer in an IT Service Company. Even before that, when he was learning computer science, J-F studied cache consistency in distributed systems and network group communication protocols.
