Data Integration tasks rules and guidelines

When you develop Data Integration mappings and tasks to use in

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

When you set up the organization in

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
