Wes McKinney created ARROW-491:
----------------------------------
Summary: [C++] Add FixedWidthBinary type
Key: ARROW-491
URL: https://issues.apache.org/jira/browse/ARROW-491
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
This would be very useful for interacting with Parquet and other data sources
that use fixed-byte-width binary types, as a more efficient version of
List<UInt8>. We can resolve adding this type to the format spec later.
[~julienledem] [~nongli] do you have an opinion about this type? Would be
equivalent to FIXED_LEN_BYTE_ARRAY in Parquet. It would be convenient to
implement Decimal types on top of this
