is selected.

To distinguish between publication tasks and subscription tasks, indicate the type of the task in the task name. When you select a task for a publication or for a subscription, you can easily select an appropriate task.

The task operation for publication tasks is an insert operation.

When you create a publication task, select the

Data Integration Hub

connection as the target. When you create a subscription task, select the

Data Integration Hub

connection as the source.

Synchronization tasks do not support multiple sources. Therefore, when you create a synchronization task for a publication or a subscription with multiple sources, create a relationship between the sources for the following use cases:

Publications: when you publish from multiple tables.
Subscriptions: when you subscribe to multiple tables, or when the subscription is a compound subscription.

The mapping operation is an insert operation for both publication and subscription mappings.

When you create a publication mapping, select the

Data Integration Hub

connection when you configure the target properties. When you create a subscription mapping, select the

Data Integration Hub

connection when you configure the source properties.
