> Batch optimized translation for Spark Runner

> Spark Runner and maybe all other runners that deal with batch only data might
> benefit of a batch optimized translation where details about the full Beam
> model matter less because we are in Global window, no panes info is needed
> and all records use the sane (min) timestamp. With this premise the records
> can be encoded as 'value only' WindowValues and transforms like GroupByKey
> may ignore windowing (GABW) to improve performance.
