Save
Read Replicas are copies of a primary database that are created to improve read performance. They are often used in applications where there is a high volume of read traffic, such as e-commerce websites or social media platforms.
Benefits of Using Read Replicas
There are several benefits to using read replicas, including:
- Improved read performance: Read replicas can significantly improve read performance by distributing read traffic across multiple servers. This can reduce the load on the primary database and make it more responsive.
- Increased availability: Read replicas can provide increased availability by ensuring that there is always a backup copy of the data in case the primary database fails.
- Scalability: Read replicas can be easily scaled to meet the demands of growing applications. New read replicas can be added to the system as needed, without affecting the performance of the primary database.
How Read Replicas Work
Read replicas are created by taking a snapshot of the primary database. This snapshot is then used to create a new database on a separate server. The read replica is then kept in sync with the primary database using a process called replication. Replication ensures that the data on the read replica is always up to date with the data on the primary database.

When to Use Read Replicas
Read replicas are ideal for applications where there is a high volume of read traffic. They can also be used to improve the availability and scalability of applications. However, read replicas are not always necessary. In some cases, it may be more cost-effective to simply use a single primary database.
