      public BaseShortUpdateByOperator(@NotNull @NotNull MatchPair pair, @NotNull @NotNull String[] affectingColumns, @Nullable @Nullable String timestampColumnName, long reverseWindowScaleUnits, long forwardWindowScaleUnits, boolean isWindowed)
      Construct a base operator for operations that produce short outputs.
      Parameters:
      pair - the MatchPair that defines the input/output for this operation
      affectingColumns - a list of all columns (including the input column from the pair) that affects the result of this operator.
      timestampColumnName - an optional timestamp column. If this is null, it will be assumed time is measured in integer ticks.
      reverseWindowScaleUnits - the reverse window for the operator. If no timestampColumnName is provided, this is measured in ticks, otherwise it is measured in nanoseconds.
      forwardWindowScaleUnits - the forward window for the operator. If no timestampColumnName is provided, this is measured in ticks, otherwise it is measured in nanoseconds.
