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 first portion of the 2 part talk, we will focus on Replication topologies, Semi-synchronous replication, 2-PC with Engine, Binlog transmittal, Binlog Server and specific MySQL server features that we developed at Facebook to improve Replication throughput and HA.
