You can use the following methods to publish data and files with Cloud Integration Hub:
Publications that trigger a Data Integration task
When the publication runs, the Cloud Integration Hub server triggers the Data Integration task that is defined for the publication and instructs the Informatica Intelligent Cloud Services data engine to retrieve the data from the publishing application. The data engine runs the Data Integration task, and transfers the source data to the topic on the Cloud Integration Hub relational publication repository.
To publish the data to multiple topics with a single task, create a compound publication. To create a compound publication, use a Data Integration mapping task.
Publications that trigger a file ingestion task
When the publication runs, the Cloud Integration Hub server triggers the file ingestion task that is defined for the publication and instructs Mass Ingestion to retrieve the files from the publishing source. Mass Ingestion runs the file ingestion task, and transfers the source files as-is to the topic on the Cloud Integration Hub file store publication repository.
Publications that publish data with an API
The Cloud Integration Hub Publish Data API publishes to a specific topic on the Cloud Integration Hub relational publication repository.
Use this method to publish small transactions from within a workflow, for example, from within Application Integration.
