Knative Eventing channels
Channels are Kubernetes Custom Resources that define a single event forwarding and persistence layer in Knative. Messaging implementations provide implementations of Channels via the ClusterChannelProvisioner object, and support different technologies, such as Apache Kafka or NATS Streaming.
Note: Cluster Channel Provisioner (CCP) has been deprecated and will be unsupported in v0.9. You should now use the Channels CRDs.
