Typical Use Cases

Reducing Read Pressure with Read/Write Splitting

RDS for PostgreSQL supports read replicas to offload read traffic from primary DB instances.

To offload read pressure on the primary DB instance, you can create one or more read replicas in the same region as the primary instance. These read replicas can process a large number of read requests and increase application throughput.

Storing Diverse Data Types

RDS can work with Distributed Cache Service (DCS) for Redis, GeminiDB Redis API, and OBS to store different types of data.
