Bidirectional Replication

Disclaimer: This lesson uses the terms bidirectional and multi-primary instead of the terms master-master and multi-master, respectively. Please refer to the PostgreSQL documentation for more details.

In a bidirectional replication setup, multiple database servers act as primary databases and receive updates from client applications. Each database server can receive writes and updates, and replicate changes to all other nodes in the cluster. This type of replication is also known as multi-primary replication.

Bidirectional replication is a bidirectional replication in which changes made to the data on one server are automatically propagated to another server, and vice versa. This setup allows for load balancing, high availability, and increased data accessibility, as the data is replicated between multiple servers.

With bidirectional replication, there is no single primary server that controls the data, as ...
