When should you use master-slave replication?

Master-slave replication in MySQL is a powerful feature that allows you to improve database performance, enable data redundancy, and ensure high availability. Here are some scenarios where you should consider using master-slave replication:

• Load Balancing: Distributing read queries across multiple slave servers can significantly reduce the load on the master server, enhancing performance.
• Backup Strategy: Regular backups can be taken from the slave database without impacting the master, ensuring that data integrity is maintained during backups.
• High Availability: In case of master server failure, you can promote a slave to master to minimize downtime, helping achieve continuous availability.
• Data Analysis: Running analytics and reporting on slave servers, so the master remains dedicated to processing transactions, can improve overall efficiency.
• Geographic Distribution: Positioning slave servers in different geographical locations can help enhance data access speeds for distributed user bases.
