State stores components

Dapr integrates with existing databases to provide apps with state management capabilities for CRUD operations, transactions and more. It also supports the configuration of multiple, named, state store components per application.

State stores are extensible and can be found in the components-contrib repo.

A state store in Dapr is described using a Component file:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: statestore
  namespace: default
spec:
  type: state.<DATABASE>
  version: v1
  metadata:
  - name: <KEY>
    value: <VALUE>
  - name: <KEY>
    value: <VALUE>
...

The type of database is determined by the type field, and things like connection strings and other metadata are put in the .metadata section. Even though metadata values can contain secrets in plain text, it is recommended you use a secret store.
