---------------------------------
Summary: Support using the new Decimal64ColumnVector for reading
and writing decimal
Key: ORC-344
URL: https://issues.apache.org/jira/browse/ORC-344
Project: ORC
Issue Type: Improvement
Components: Java
Reporter: Owen O'Malley
Assignee: Owen O'Malley
Hive just added Decimal64ColumnVector for faster operations on decimal objects
that are <= 18 digits of precision.
I propose:
* We create a new method in TypeDescription to create the VectorizedRowBatch
with the new Decimal64ColumnVector.
* Have the reader and writer detect the ColumnVector type and call the right
internal method.
This leaves current clients working using the current ColumnVector. Clients can
chose when to transition to the new interface.
