Automatic Pass-through File Subscription

Use this type of subscription to consume files that were published to topics that use a file publication repository and that provide files as-is, without loading them to a relational database, if you want

Data Integration Hub

to create the PowerCenter workflow for the subscription.

You cannot deliver the files with a pass-through file target to a Hadoop Distributed File System (HDFS).

For subscriptions with a pass-through file target, define the location of the target files, and then define the expected file names or the expected file name patterns for the tables in the topic that is associated with the subscription.

If you use the file transfer protocol to move the files, select the file transfer connection.

Data Integration Hub

creates the mapping based on the topic tables that are associated with the file. Topic tables that are not associated with a file are not mapped. You can edit the mapping of fields and exclude fields and tables. For each table that exists in the mapping, the subscription process generates a file. The file contains only the fields that are mapped from the topic to the target.

The following pages appear in the subscription wizard for this type of subscription:

General. Define basic subscription properties.

Processing.

If you want to run a post-process on the subscription, select a subscription post-processing workflow. If the post-process includes parameters, the parameters appear in this page and are optional. If required, set the values of the parameters.

Target. Choose the target type. If you use file transfer, select the connection to the target to which

Data Integration Hub

delivers the data. Enter the location of the file or files that

Data Integration Hub

delivers, and name the file or files that

Data Integration Hub

writes to the target. You must name a file target for at least one topic table.

Filter.

Define the data that the subscription consumes by setting filter conditions on the file metadata.

Schedule. Define the method and the frequency of data consumption. You can select to consume the published data immediately after the data is ready, to run the subscription manually or by an external trigger, or to consume the data according to a schedule that you define.

Delivery. Define the delivery options of the data to consume. For subscriptions that run either manually or by an external trigger or that run by schedule, choose the data delivery scope and delivery format: all available publications or the latest publication.
