>                 Key: ARROW-491

>             Project: Apache Arrow
>          Issue Type: New Feature
>          Components: C++
>            Reporter: Wes McKinney
>            Assignee: Wes McKinney
>            Priority: Major
>             Fix For: 0.3.0

>
> 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
