> When insert data into AlignedTVList like this way.Insert 1000 rows of d1.s1 by tablet interface, then insert 1000 rows of d1.s2.

> The current logic will only calculate the black and purple part of memory cost. 
> Beside, the calculation of purple part is not correct.
> The correct calculation is acquired array number * memory size of an array, however, the current is acquired array number * memory size of a data point.
