What does Feast apply do?
1.
Feast will scan Python files in your feature repository and find all Feast object definitions, such as feature views, entities, and data sources.
2.
Feast will validate your feature definitions
3.
Feast will sync the metadata about Feast objects to the registry. If a registry does not exist, then it will be instantiated. The standard registry is a simple protobuf binary file that is stored on disk (locally or in an object store).
4.
Feast CLI will create all necessary feature store infrastructure. The exact infrastructure that is deployed or configured depends on the provider configuration that you have set in feature_store.yaml. For example, setting local as your provider will result in a sqlite online store being created.
feast apply (when configured to use cloud provider like gcp or aws) will create cloud infrastructure. This may incur costs.
