Paul Rogers commented on DRILL-5993:
------------------------------------
Although you cannot write to random location is non-fixed-width vectors, there
is a work around.
Write to the vectors in sequential order. But, use a selection vector (SV2) to
provide a logical ordering. Pass the SV2 through the Selection Vector Remover
(SVR) to rewrite the vector in the desired order.
Still, what is the problem being solved here?
