----------------------------
Summary: [C++] Support dedicated ColumnVectorBatch of numeric types
Key: ORC-1298
URL: https://issues.apache.org/jira/browse/ORC-1298
Project: ORC
Issue Type: Improvement
Components: C++
Reporter: Gang Wu
Assignee: Hao Zou
Now the C++ reader and writer use LongVectorBatch for BYTE, SHORT, INT and LONG
types and DoubleVectorBatch for FLOAT and DOUBLE types. Then it is user's
responsibility to guarantee no overflow happens. It would be great if we can
support type-specific ColumnVectorBatch for these types. As this is a
public-facing API, we may provide WriterOptions and ReaderOptions to enable it
explicitly and turn in off by default.
