Publication and Subscription process

The publication process starts on the schedule that you define in the publication

, when an external process triggers the publication,

or when you manually run the publication.

When data transfer is complete, the topic data set is ready for subscribers. The subscription process starts when one of the following conditions exist, based on the configuration of data consumption in the subscriptions:

When data is published to the topic.

When all publishers that publish to the topic finish publishing.

If the topic to which the data is published has subscribers,

Cloud Integration Hub

triggers a

Cloud Integration Hub

subscription workflow for each subscriber, to consume the data.

Cloud Integration Hub

generates events to track the progress of the publication and subscription process. When an application publishes data,

Cloud Integration Hub

creates a parent publication event. When the publication process ends and the published data is ready to consume,

Cloud Integration Hub

generates a child event for each subscription.

The events change status as the publication and subscription process progresses, and reach a completed status after the process ends successfully. You also use events to monitor and troubleshoot issues that might occur during the process.

During the publication or the subscription process,

Cloud Integration Hub

communicates with

Informatica Intelligent Cloud Services

Cloud Integration Hub

server triggers the Data Integration task that is defined for the publication through an

Informatica Intelligent Cloud Services

REST API.

For cloud publications, the target is defined using a
