A Participant is a component that acts as a bridge between the CLAMP runtime and components such as the Policy Framework, DCAE, or a Kubernetes cluster that are taking part in control loops. It listens to DMaaP to receive messages from the CLAMP runtime and performs operations towards components that are taking part in control loops. A participant has a Control Loop Element for each control loop in which it is taking part.
The implementation of a participant may use a common ParticipantIntermediary library, which carries out common message and state handling for Control Loop Elements in participants. The ParticipantImpelementation is the component specific implementation of a participant, which is specifically developed for each component that wishes to take part in control loops.
