Database Replication | System Design | High Level Design
Welcome to a concise guide on database replication in system design!
Join me as I explore this critical technique for enhancing data availability and reliability.
What is Database Replication?
Database replication involves copying data from one database server (the primary) to one or more secondary servers, ensuring that the same data is available on multiple systems.
Types of Database Replication
Master-Slave Replication: One primary server (master) handles writes, while one or more secondary servers (slaves) handle reads.
Master-Master Replication: Multiple servers handle both reads and writes, ensuring high availability and fault tolerance.
Synchronous Replication: Data is copied to secondary servers in real-time, ensuring consistency but potentially increasing latency.
Benefits of Database Replication
High Availability: Ensures data is always available, even if one server fails.
Load Balancing: Distributes read requests across multiple servers, improving performance.
Disaster Recovery: Provides backups that can be used to restore data in case of failure.
Geographic Distribution: Allows data to be replicated to different geographic locations, reducing latency for global users.
In upcoming episodes, I'll dive deeper into database replication, providing practical examples and discussing best practices. Don’t forget to like, share, and subscribe to stay updated! Let’s master the art of database replication together!
