We looked at skipping v8 columns and creating v9 columns directly for Druid 0.7.0. It turns out that creating v8 followed by conversion to v9 is still faster than creating v9 columns directly in the current incarnation of the code, due to the fact that v8 serialization walks the rows once to create all the columns vs. v9 code still requires walking the rows multiple times.

With #3688 merged I think this issue can be closed.
