Data Integration Tasks Rules and Guidelines

Data Integration Tasks Rules and Guidelines

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:
  • Do not 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.
  • 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
    ,
    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_<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
    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.
