Subscription process for subscriptions that trigger Data Integration tasks

Subscription process for subscriptions that trigger Data Integration tasks

When a subscription triggers an
Data Integration
 task, the subscription process includes retrieving the required data from the
Cloud Integration Hub
 relational publication repository, running the subscription task, and writing the data to one or more subscriber targets.
Cloud Integration Hub
 keeps the data in the publication repository until the retention period of the topic expires.
The subscription process includes the following stages:
  1. When the publication is ready for subscribers, the
    Cloud Integration Hub
     server triggers the Data Integration task that is defined for the subscription through an
    Informatica Intelligent Cloud Services
     REST API.
  2. The subscription process uses the
    Cloud Integration Hub
     cloud connector to read data from
    Cloud Integration Hub
    .
  3. The Data Integration task reads the data from
    Cloud Integration Hub
     and then writes the data to the subscribing application.
  4. The
    Cloud Integration Hub
     server changes the status of the subscription event to complete.
  • For better performance,
    Cloud Integration Hub
     writes the data to a folder on the local server for intermediate staging, and then writes the data to the target location.
    Cloud Integration Hub
     deletes the data from the local server at the end of the subscription process.
  • You can sort data only for the fields that are enabled as
    Filter accelerator
    .
  • You can't sort a
    String
     data type with a precision greater than 1024.
  • You can filter or sort data based on one or more fields. You can sort the fields in ascending or descending order.
