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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
