Activator is the event triggering system inside Microsoft Fabric. It's related to Real-Time Intelligence to trigger actions based on the data.

However, Activator can also trigger events related to Fabric objects and one of the best features is triggering events based on file events in lakehouses.

This feature makes it easier to use the lakehouse as a drop zone in a medallion architecture. Instead of requiring a drop zone in azure before ingesting into the lakehouse, the lakehouse itself can be the drop zone.

Combining features such as triggers over lakehouse files, SAS authentication in OneLake and more, we can build the drop zone of a medallion architecture inside a Fabric lakehouse.

In this way, we can bring the entire medallion architecture to inside Fabric
