Full Replication
Full replication, also known as whole database replication, is a strategy where the entire database is replicated to one or more destination servers. This means that all tables, rows, and columns in the database are copied to the destination servers, ensuring that the replicas have an exact copy of the original database.
For Example:
An e-commerce website uses full replication to replicate its entire product catalog and customer database to multiple servers. This ensures that all product information and customer data are available on all servers, providing high availability and fault tolerance.
Database Replication in System Design
Database replication is a crucial concept in system design, especially for ensuring data availability, reliability, and scalability. It involves creating and maintaining multiple copies of a database across different servers to enhance performance and fault tolerance. In this article, we will delve into the fundamentals of database replication, its various types, and its importance in system design.
