MySQL/MariaDB Parallel Replication: inventory, use-cases and limitations
In the last 24 months, MySQL/MariaDB replication speed has improved a lot thanks to parallel replication. MySQL and MariaDB have different types of parallel replication; in this talk, I present the different implementations, with their limitations and the corresponding tuning parameters. I cover what to do to make parallel replication faster and what to avoid for maximizing parallel replication benefits. I also present benchmark results from real Booking.com workloads. Finally, I discuss some deployments at Booking.com that take advantage of parallel replication speed improvements.
Senior System Engineer, Booking.com
Since joining Booking.com in October 2013, Jean-François is working on growing the MySQL installations by removing replication bottlenecks (he also works on other engineering problems that are less relevant here). One of his latest project is the Binlog Server but he also has an in deep understanding of GTIDs and parallel replication (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 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 system and network group communication protocols.
