For subscriptions that trigger Data Integration tasks, the subscription schedule defines the frequency of the subscription. You can consume published data when it is published, manually, by an external trigger, or at defined intervals. If you create a compound subscription, you can only choose to consume data when it is published, manually, or by an external trigger.
Consumption of data by the subscription starts when one of the following conditions exist:
•The subscription schedule is set to consumes data immediately after the publisher publishes the data to Cloud Integration Hub.
•The scheduled start time arrives.
•You start the subscription from a REST API.
•You manually run a subscription.
•You manually get previous publications.
In Administrator, you can set a blackout period during which the scheduled Data Integration subscriptions and scheduled Mass Ingestion file subscriptions don't run.
