Locality of data

Catching

The purpose of caching:

• To eliminate the need, in many cases, to request information the caller already has

• To eliminate the need, in many other situations, to send full HTTP responses

Mirror data

Replacing a query to another microservice with a query to the microservice’s own database by creating a read model: a data model that can be queried easily and efficiently.

Read models are often based on events from other microservices.

Read models can also be built from responses to queries to other microservices
