Azure Database for MySQL: Read replica now generally available

Published date: February 25, 2019

Azure Database for MySQL now supports continuous asynchronous replication of data from one Azure Database for MySQL server (master) to up to five Azure Database for MySQL servers (replicas) in the same region. This allows read-heavy workloads to scale beyond the capacity constraints of one Azure Database for MySQL server and to be balanced across replica servers according to users' preference. Replica servers are read-only except for writes replicated from data changes on the master. Stopping replication to a replica server causes it to become a standalone server that accepts reads and writes.
