> Key: SAMZA-914
> URL: https://issues.apache.org/jira/browse/SAMZA-914
> Project: Samza
> Issue Type: Bug
> Reporter: Yi Pan (Data Infrastructure)
> Assignee: Yi Pan (Data Infrastructure)
> Attachments: SAMZA-914_ operator Java programming API - Google
> Docs.pdf, rb47835 (1).patch
>
>
> In the process of design/refining the physical operator layer for SAMZA-552,
> there is a need to design/implement a set of 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.
