> Currently, one insert will calculate an int array to record index information of AlignedTVList and values in InsertPlan. This calculation will traverse the measurement list twice.
> However, this logic can be simplified by traverse only once. We can just use a new values Object array, move the origin values to this new array which matches the order of the AlignedList, and then insert the new values into TVList.
