> Vectorize a submit of current PTFOperator window function support. The first
> phase doesn't include custom PRECEDING / FOLLOWING window frame clauses.
> Since we don't have unbounded support yet (i.e. spilling to disk) the enable
> variable hive.vectorized.execution.ptf.enabled is off by default.
