Ismaël Mejía updated BEAM-12135:
--------------------------------
Description: 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 the we are in the 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. (was: Spark Runner and maybe
all other runners that deal with batch only data might benefit of a batch
optimized translation where internal records are encoded as 'value only'
WindowValues and operations like GroupByKey may ignore windowing (GABW) to
improve performance.)
