GCP PubSub Subscriber Agent

Subscribers are registered listeners on a subscription to receive messages. Subscribers interact with Pub/Sub service to read messages from the pull subscriptions.

In order to receive messages published on a topic, a subscription must be created for that topic. Only messages that are published to the topic after the subscription is created, are available to subscriber applications. When a message is sent to a subscriber, the subscriber should acknowledge the message. Without the acknowledgment, the message is considered to be outstanding and PubSub will repeatedly attempt to redeliver these messages to the subscriber. This,

however, will not be delivered to other subscribers within the same subscription.

GCP PubSub Subscriber agent is available as a collection agent in Real-Time workflows.
