Joris Van den Bossche created ARROW-5890:
--------------------------------------------

             Summary: [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


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}}
