/**
 * Eventarc processes events generated by an event provider and delivers them to
 * a subscriber.
 *
 * An event provider is a software-as-a-service (SaaS) system or
 * product that can generate and deliver events through Eventarc.
 *
 * A third-party event provider is an event provider from outside of Google.
 *
 * A partner is a third-party event provider that is integrated with Eventarc.
 *
 * A subscriber is a GCP customer interested in receiving events.
 *
 * Channel is a first-class Eventarc resource that is created and managed
 * by the subscriber in their GCP project. A Channel represents a subscriber's
 * intent to receive events from an event provider. A Channel is associated with
 * exactly one event provider.
 *
 * ChannelConnection is a first-class Eventarc resource that
 * is created and managed by the partner in their GCP project. A
 * ChannelConnection represents a connection between a partner and a
 * subscriber's Channel. A ChannelConnection has a one-to-one mapping with a
 * Channel.
 *
 * Publisher allows an event provider to publish events to Eventarc.
