> BeamRelNode exposes PCollection<BeamRecord> buildBeamPipeline() which builds
> a pipeline when parsing.
> It feels like it should instead implement a
> PTransform<PCollection<BeamRecord>, PCollection<BeamRecord>> which would
> receive a prepared PCollection, and apply sub-expressions instead of manually
> invoking expression evaluation to get the input.
> And maybe consider building it lazily.
