>                 Key: ARROW-13388
>                 URL: https://issues.apache.org/jira/browse/ARROW-13388
>             Project: Apache Arrow
>          Issue Type: New Feature
>    Affects Versions: 4.0.1
>            Reporter: Jorge Leitão
>            Priority: Minor
>
> While trying to read a utf8 column with DELTA_BYTE_ARRAY encoding, pyarrow 
> yields
> `OSError: Not yet implemented: Unsupported encoding.`
> It would be nice to have support for this encoding, since it lends itself 
> really well to the arrow format, whereby values's encoding is equal to 
> arrow's representation.
