• For example, a Google Compute Engine instance can write logs to the monitoring system, to a database for later querying, and so on. Data streaming from various processes or devices. For example, a residential sensor can stream data to backend servers hosted in the cloud. Reliability improvement.
• This sensor operator will pull up to ``max_messages`` messages from the specified PubSub subscription. When the subscription returns messages, the poke method's criteria will be fulfilled and the messages will be returned from the operator and passed through XCom for downstream tasks.

• When a blocking mode is used, the calling thread for each send call is blocked until the API can accept the message. As a result, the application automatically controls the flow of send calls to a rate at which the event broker can accept them. A send call remains blocked until either it is accepted by the API, or the blocking write timer expires.
