Import to Hub

The Import to Hub stage defines a new model or populate an existing model from two incoming channels of data. It includes an optional outgoing error port that collects records not successfully processed by the dataflow.

The Import to Hub stage is used to create a complex network of relationships called a hub, which can be displayed in a model. It can also be used to populate an existing model. Once a model is created, it can be queried against in a Read From Hub stage or a Query Hub stage, and it can be visualized in Metadata Insights or the Relationship Analysis Client.

A dataflow that uses an Import to Hub stage requires two incoming channels of data: one for entities and one for relationships. You'll then need to complete the Entities tab and the Relationships tab in the Import to Hub stage to complete your dataflow and create or update your model.
