Assignee: Alessandro Molina
> [Python] Add an helper method to decode a DictionaryArray back to a plain
> Array
> -------------------------------------------------------------------------------
>
> Key: ARROW-12492
> URL: https://issues.apache.org/jira/browse/ARROW-12492
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Reporter: Alessandro Molina
> Assignee: Alessandro Molina
> Priority: Minor
>
> To create a DictionaryArray pyarrow currently offers the
> {{Array.dictionary_encode}} helper, but there is a lack of an obvious way to
> do the reverse. A {{DictionaryArray.decode}} helper could provide an
> immediate obvious solution to get back an unrolled Array from the dictionary
> encoded version.
