PubSub Beat

Version 6.0.3

Cloud Pub/Sub brings the flexibility and reliability of enterprise message-oriented middleware to the cloud. At the same time, Cloud Pub/Sub is a scalable, durable event ingestion and delivery system that serves as a foundation for modern stream analytics pipelines. By providing many-to-many, asynchronous messaging that decouples senders and receivers, it allows for secure and highly available communication among independently written applications.


  • Topic. A named resource to which messages are sent by publishers.
  • Subscription. A named resource representing the stream of messages from a single, specific topic, to be delivered to the subscribing application. For more details about subscriptions and message delivery semantics, see the Subscriber Guide.
  • Message. The combination of data and optional attributes that a publisher sends to a topic and is eventually delivered to subscribers.
  • Message attribute. A key-value pair that a publisher can define for a message. For example, key and value en could be added to messages to mark them as readable by an English-speaking subscriber.
