Subscription methods

You can use the following methods to consume data and files with

Subscriptions that trigger a Data Integration task: When the subscription runs, the
Cloud Integration Hub
server triggers the
Data Integration
task that is defined for the subscription and instructs the
Informatica Intelligent Cloud Services
data engine to retrieve the data from the topic or topics on the
Cloud Integration Hub
publication repository. The data engine runs the
Data Integration
task, and transfers the data to the subscribing application. To consume data from multiple topics with a single task, create a compound subscription.
For subscriptions that trigger a
Data Integration
task you can define the delivery behavior for the published data, for example, to aggregate all data sets to a single data set, or to consume the latest published data set. You can also configure a retry policy that defines the number of times
Cloud Integration Hub
retries to run the subscription in case of failure and the retry interval.

Use this method to consume batch data from the relational publication repository into files, applications, and repositories.
Subscriptions that trigger a file ingestion task: When the subscription runs, the
Cloud Integration Hub
server triggers the file ingestion task that is defined for the subscription and instructs
Mass Ingestion
to retrieve the files from a specific topic on the
Cloud Integration Hub
publication repository.
Mass Ingestion
runs the file ingestion task, and transfers the files to the subscriber target.
Use this method to consume files as-is from the file store publication repository.
Subscriptions that consume data with an API: The
Cloud Integration Hub
Consume Data API consumes data from a specific topic on the
Cloud Integration Hub
publication repository.
Use this method for high frequency, event-driven subscriptions. For example, to consume data that is published with the Publish Data API.
