Partitioning is a feature of MySQL that has been around since version 5.1. It is a method of improving database speed beyond the limits of indexes and available memory. When used appropriately, it can increase performance by several orders of magnitude. Amid some doubts, it was overshadowed by more flamboyant features in MYSQL 5.5.
Starting with MySQL 5.6, and continuing with MariaDB 10.0 and MySQL 5.7, there has been a rush of new replication features: * Parallel replication * Global Transaction Identifiers * Multi source replication * Crash safe tables. How good are these features?
Database replication, in its simplest definition, is just data flowing from a master to some slaves. Until recently, the most daring topologies adopted by DBAs was a master-to-master deployment, with perhaps a DRBD in between. The times of circular replication are over!
