Owen O'Malley reassigned ORC-344:
---------------------------------
> 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
> Priority: Major
>
> 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.
