MySQL/MariaDB Parallel Replication: inventory, use cases and limitations

MySQL/MariaDB Parallel Replication: inventory, use cases and limitations

Experience level: 
50 minutes conference
Business / Case Studies
Tools and Techniques


In the last 24 months, MySQL/MariaDB replication speed has improved a lot, thanks to parallel replication. MySQL and MariaDB Server have different types of parallel replication; in this talk, I present the different implementations which will allow us to understand their limitations and tuning parameters. I am covering how to make parallel replication faster and what to avoid for maximizing its benefits. I also present benchmark results from workloads. Finally, I discuss some deployments at that take advantage of parallel replication speed improvements.

Jean-François Gagné

Senior System Engineer,


Since joining 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, 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.
