Owen O'Malley commented on HIVE-17235:
--------------------------------------

I think we should make a new type that looks like:

{code}
class Decimal64ColumnVector extends ColumnVector {
  long[] vector;
  int precision;
  int scale;
}
{code}

It will be extremely fast and provide a fast conduit to ORC. 

> Add ORC Decimal64 Serialization/Deserialization
