      Description

      Right now there is a mixture of different kinds of loops within aggregate functions. Although performance is not the main goal at the moment, we should focus on performant execution especially in this runtime functions.

      e.g. DataSetTumbleCountWindowAggReduceGroupFunction

      We should replace loops, maps etc. by primitive while loops.
