Joris Van den Bossche updated ARROW-5890:
-----------------------------------------
Fix Version/s: 1.0.0
> [C++][Python] Support ExtensionType arrays in more kernels
> ----------------------------------------------------------
>
> Key: ARROW-5890
> URL: https://issues.apache.org/jira/browse/ARROW-5890
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Joris Van den Bossche
> Priority: Major
> Fix For: 1.0.0
>
>
> From a quick test (through Python), it seems that {{slice}} and {{take}}
> work, but the following not:
> - {{cast}}: it could rely on the casting rules for the storage type. Or do we
> want that you explicitly have to take the storage array before casting?
> - {{dictionary_encode}} / {{unique}}
