>
> LazyBinarySerDe.serialize() ends up making
> getCategory()/getPrimitiveCategory() calls for every column of every row.
> Tried some simple tests to eliminate these calls for the non-vectorized
> version, this looks like it speeds up the writes by ~3x.
> Adding a LazyBinarySerDe2 class with this new implementation.
