Data Integration Hub Workflows Overview
A Data Integration Hub workflow is a set of instructions that define one of the following actions:
- •How to process data that on-premise applications publish to and consume from the Data Integration Hub publication repository with custom publications and subscriptions. A Data Integration Hub workflow for custom publications and subscriptions can be based on a PowerCenter workflow, Data Engineering Integration mapping and workflows, Data Engineering Streaming mapping, or Data Quality mapping and workflows.
- •How to pre-process data before you publish it. A Data Integration Hub pre-processing workflow must be based on a PowerCenter workflow.
- •How to post-process data to which you subscribe. A Data Integration Hub post-processing workflow must be based on a PowerCenter workflow.
- •What action to take when publication or subscription events are in a defined status, as defined in event monitoring rules that invoke a PowerCenter workflow. A Data Integration Hub workflow for monitoring rules must be based on a PowerCenter workflow.
Before you create a workflow in Data Integration Hub, you must create the relevant PowerCenter workflow, Data Engineering Integration mapping or workflow, Data Engineering Integration streaming, Data Quality mapping or workflow. For more information, see the following sections:
You then select the workflow or mapping when you create the
Data Integration Hub workflow. For more information, see
Creating a Data Integration Hub Workflow.
When the operator creates the publication or subscription or the monitoring rule, they select the Data Integration Hub workflows to use, as applicable.
You do not need to create a Data Integration Hub workflow for the following publication and subscription types:
- •Publications and subscriptions that use an automatic mapping. Data Integration Hub creates a PowerCenter workflow and mapping directly from the publication or subscription.
- •Publications and subscriptions for cloud applications. The operator selects an Informatica Intelligent Cloud Services task when they create the publication or the subscription.
