This is how data engineers and data scientists think. b. … Fluent API is an advanced way of specifying model configuration that covers everything that data annotations can do in addition to some more advanced configuration not possible with data annotations. It defines dependencies across actions as opposed to defining a control flow. The builder pattern and fluent interfaces seem similar at first glance because they both use method chaining. The Java Fluent API Designer Crash Course. The annotations only cover a subset of the fluent API functionality, so there are mapping scenarios that cannot be achieved using annotations.

As with all fluent interfaces, there is no point looking at strict API documentation (JavaDoc for Java), and you're better looking at example code, and this page is it (perhaps the blog entries of others too).
