> In the process of design/refining the physical operator layer for SAMZA-552, there is a need to design/implement a fluent programming APIs s.t. users may be able to directly write Java programs using the physical operators.
> The programming APIs would serve as an intermediate layer that serves the following purposes:
> # Users can choose to directly use physical operators (like window/join/filter etc.) in their Java code
> # The SQL parser and engine can use this API to construct the physical operators and the execution DAG.
