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.
Equality
Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection>
objects compare equal. Objects that compare equal share the same underlying resources.
Performance
Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.
Thread Safety
Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.
