> Translate physical Table API plan into DataSet program
> ------------------------------------------------------
>
> Key: FLINK-3227
> URL: https://issues.apache.org/jira/browse/FLINK-3227
> Project: Flink
> Issue Type: Sub-task
> Components: Table API
> Reporter: Fabian Hueske
> Assignee: Timo Walther
>
> The RelNode tree generated by FLINK-3226 is a 1-to-1 representation of the
> final DataSet API program. Hence, the translation step only needs to create
> corresponding operators with correct keys and user-functions. User-functions
> are implemented as RichFunctions that wrap generated code. In a first
> version, the wrapping functions are parameterized with a source code string
> which is generated during the program construction. As a first step, we can
> reuse much of the code generation logic of the current Table API.
> The source code string is compiled in the open() method of the wrapping
> function and later invoked by the wrapper.
