Implement Replication in Postgresql Using Docker Containers

Implementing replication during database design is always a best practice. It will protect our data if the master system fails, you won’t lose any data. To understand how the replication works, I came up with the idea of implementing it in between two docker containers. This setup allows anyone to test replication on a single machine without needing an extra server.

Data Linking

Benefits of having Replica Server:

• High Availability: Ensures minimal downtime by allowing a replica server to take over if the primary server fails.
• Disaster Recovery: Provides data redundancy and faster recovery in case of hardware failure or data corruption.
• Load Balancing: Offloads read-heavy operations to the replica, improving overall system performance.
• Data Integrity: Keeps data consistent across multiple servers, reducing the risk of data loss or corruption.
• Non-Disruptive Backups: Allows backups to be performed on the replica server without affecting the primary server’s operations.
• Safe Testing Environment: Enables testing of new queries on the replica server before applying them to the primary server.
• Enhanced Security: Let you run important tasks on the replica server, keeping the main server…
