Database Replication

Database replication is a technique used to create and maintain multiple copies of a database, often referred to as replicas. The purpose of replication is to provide redundancy, improve availability, and distribute the load for both read and write operations.

Benefits of Database Replication

Load Distribution: Read queries can be directed to the replicas, reducing the load on the primary database and improving overall performance.

Redundancy: Replicas serve as backups in case of data loss or corruption on the master database.

Geographic Distribution: Replicas can be located in different geographic regions, providing lower latency access for users in different parts of the world.

High Availability: Replication provides failover capability. If the master database goes down, one of the replicas can take over, minimizing downtime.
