Cloud Integration Hub

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
publication repository, running the subscription mapping, 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 cloud application.
  4. The
    Cloud Integration Hub
    server changes the status of the subscription event to complete.
For performance tuning purposes,
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.
