> There is a use case where users want to mix Beam programming model with Beam SQL together to process a dataset. The following is an example of the use case:
> dataset.apply(something user defined)
>             .apply(SELECT ...)
>             .apply(something user defined)
> As you can see, after the SQL statement is applied, the data structure should be preserved for further processing.
> Make struct flattener configurable in PlannerImpl to allow disabling it when not needed can be a solution.
