Each Publication event also shows the consumption status of the child Subscription events. The status reflects the overall consumption and changes after all Subscription events changed status. For example, the consumption status changes to complete after all subscribers finished consuming the published data.

For subscriptions,

Data Integration Hub

assigns the following event statuses:

Delayed. Indicates that the published data is ready but that the subscribing application did not start consuming the data.
Processing. Indicates that the subscription instance is running.
Completed. Indicates that the subscription instance finished running and that the subscribing application consumed all published data.
Error. Indicates that the subscription instance encountered errors and did not finish running.
