Decorators in Go using embedded structs

Our decorator should implement the same interface functions as the wrapped type and forward function calls to the wrapped object with some extra functionality. Because the decorator implements the same interfaces as the type it wraps they are interchangeable.

In short, a seriously impressive feat of engineering. Before the acquisition its creators often touted the concept of “layers”, meaning stateless programs which add new features to the otherwise simple database. A SQL layer could make FoundationDB behave like a relational database while an AMQP layer could make it function as a message broker.
