When you develop Data Integration mappings and tasks to use in Cloud Integration Hub publications and subscriptions, consider these rules and guidelines.
General rules and guidelines
Consider the following rules and guidelines when you create Data Integration mappings and tasks:
•Don't run tasks that you create for Cloud Integration Hub from within Informatica Intelligent Cloud Services. You must run the tasks from Cloud Integration Hub by running the publication or the subscription to which the task is associated.
•Don't check the Data Integration task into a source control repository if you use it in a Cloud Integration Hub publication or subscription.
•When you use the Cloud Integration Hub connection, the target object in a publication mapping or task and the source object in a subscription mapping or task presents the list of topics defined in Cloud Integration Hub. The format of the list is TopicName/tableName.
Warning: When you set up the organization in Cloud Integration Hub, Cloud Integration Hub creates the connection Cloud Integration Hub in the organization in Informatica Intelligent Cloud Services. Do not rename or edit this connection. Editing the connection or changing the connection name might result in errors at run time.
•Cloud Integration Hub determines the scheduling of the publication or the subscription based on the settings that the operator defined for the publication or the subscription. When you create the Data Integration task, in the Schedule page of the task wizard, verify that the option Do not run this task on a schedule 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.
For example, name a publication task Pub_relational_<TaskName>, and name a subscription task Sub_relational_<TaskName>.
Synchronization task rules and guidelines
Consider the following rules and guidelines when you create synchronization tasks and mappings:
•The task operation for publication tasks is an insert operation.
•When you create a publication task, select the Cloud Integration Hub connection as the target. When you create a subscription task, select the Cloud 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.
•Cloud Integration Hub supports the following connection types in synchronization tasks that you create for subscriptions in Cloud Integration Hub:
- Relational database
- Salesforce
- Flat file
Mapping task rules and guidelines
Consider the following rules and guidelines when you create mapping tasks and mappings:
•The mapping operation is an insert operation for both publication and subscription mappings.
•When you create a publication mapping, select the Cloud Integration Hub connection when you configure the target properties. When you create a subscription mapping, select the Cloud Integration Hub connection when you configure the source properties.
