Disclosed are some implementations of systems, apparatus, methods and computer program products for implementing a polling command strategy in a database system. A subscriber transmits, to a database system, a subscription to an event. When the database system detects the event, a publisher transmits a message notifying the subscriber of the occurrence of the event. The subscriber processes the message received from the publisher. Responsive to processing the message, the subscriber waits a predefined period of time. After waiting the predefined period of time, the subscriber sends a polling message to the database system. Responsive to the polling message, the subscriber obtains data satisfying the subscription from the database system and the subscriber processes the data.
