Define Feature Views with Feast
Declare entities and features in a registry.
The Building Blocks
In Feast you describe features with code: an Entity, a data source, and a Feature View. Get these three right and the rest follows. 🏗️
What an Entity Is
An Entity is the thing your features describe, like a driver or a customer. It is the key you will look features up by later.
driver = Entity(name="driver", join_keys=["driver_id"])All lessons in this course
