A storage schema that supports entity types with dynamic field definitions.
A storage schema that implements this interface can react to the entity type's field definitions changing, due to modules being installed or uninstalled, or via field UI, or via code changes to the entity class.
For example, configurable fields defined and exposed by field.module.
