zzsmdfj commented on FLINK-13731:
---------------------------------
[~GatsbyNewton] , when rowTime is processTime, I not sure. In fact, I am not
clear why we not support window with alignment(calcite support for this
feature). get more operands from groupExpr in LogicalWindowAggregateRule, then
pass into case class TumblingGroupWindow or SlidingGroupWindow. is it right way
to this?
> flink sql support window with alignment
