Managing state in Dapr
In a microservice architecture, state refers to the collection of information that defines the context in which the microservice operates. In this section, we will learn how state can be managed and how Dapr does it.
State, stateless, and stateful
The way state is managed defines whether a microservice is stateful (when it takes the responsibility of persisting the state upon itself) or stateless (when the state is not in its scope of responsibility).
An example of a stateful microservice would be a shopping cart microservice that keeps the list of items in a central location (such as a database) so the customer can transparently migrate between different devices to continue their shopping experience. The shopping cart microservice could be designed by keeping the state in the host/node memory and enforcing a policy at the load balancer level to route all further interactions from the client to the original node.
Would it be a good idea...
