MySQL Replication and HA at Facebook - Part 2

Wednesday 2:55 PM - 3:55 PM

@ Hill Country C


50 minutes conference



The MySQL replication and HA suite of tools and technologies ensure that we have efficient and safe replication at Facebook scale. In spite of different kinds of process and system failures, MySQL continues to safely replicate trillions of transactions a year. The MySQL Replication/HA stack at Facebook, which delivers this scale involves Facebook enhanced Semi-Sync replication plugin, Binlog Server and high-availability suite of tools called DBStatus, Logtailer and FastFailover. Come learn about these exciting technologies and how we handle these challenges of scale.

In the second portion of the 2 part talk, we will focus on automations we've been building on top of FB MySQL replication technologies. The automations maintains MySQL high availability by dealing with both day-to-day hiccups to large scale disasters. The automation areas we will cover include automatic master failover, data consistency invariants, replication failure domain, power-loss failure recovery and continuous disaster drills.
