Public preview: Read replicas for Azure Database for MySQL
Published date: 26 September, 2018
Now in preview, Azure Database for MySQL supports continuous asynchronous replication of data from one server (“master”) to up to five servers (“replicas”) in the same region. This allows read-heavy workloads to scale beyond the capacity constraints of one server and be balanced across replica servers according to users’ preferences.
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 stand-alone server that accepts reads and writes.
