Clark Zinzow commented on ARROW-5890: ------------------------------------- Does allowing extension type implementers to register a cast function sound reasonable? I might be able to take a stab at this (just casting) in the coming months. > [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 > > 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}} -- This message was sent by Atlassian Jira (v8.20.10#820010)
