Synchronous mode of replication

The synchronous mode of replication (also known as hard synchronous mode) ensures that the Secondary host acknowledges, before completing the update at the Primary. In the case of a problem such as a network failure, it ensures that the update fails at the Primary itself.

The synchronous mode of replication is most effective in the following scenarios:

Application environments that have lower update rates but require all the hosts to always reflect the same data
Applications where lag in updates between the Primary and Secondary host is not acceptable
