When you develop Data Integration mappings and tasks to use in
Data Integration Hub
publications and subscriptions
with custom mappings
, consider these rules and guidelines.
General rules and guidelines
Consider the following rules and guidelines when you create Data Integration mappings and tasks:
Do not run tasks that you create for
Data Integration Hub
from within
Informatica Intelligent Cloud Services
. You must run the tasks from
Data Integration Hub
by running the publication or the subscription to which the task is associated.
When you use the
Data 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
Data Integration Hub
. The format of the list is
TopicName
.
tableName
.
Data 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_<TaskName>
, and name a subscription task
Sub_<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
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.
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
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.
