docs In-memory In-memory Detailed documentation on the In Memory pubsub component
/operations/components/setup-pubsub/supported-pubsub/setup-inmemory/

The in-memory pub/sub component operates within a single Dapr sidecar. This is primarily meant for development purposes. State is not replicated across multiple sidecars and is lost when the Dapr sidecar is restarted.

Component format

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: pubsub
spec:
  type: pubsub.in-memory
  version: v1
  metadata: []

Note: in-memory does not require any specific metadata for the component to work, however spec.metadata is a required field.
