[jira] [Commented] (ARROW-14043) [Python] Add support for unsigned
indexes in dictionary array?
[ https://issues.apache.org/jira/browse/ARROW-14043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17417967#comment-17417967 ]
Joris Van den Bossche commented on ARROW-14043:
-----------------------------------------------
Good catch, this was only relatively recently relaxed in the format spec, and implemeneted in C++ (https://github.com/apache/arrow/pull/7567, https://issues.apache.org/jira/browse/ARROW-9287). Seems we forgot to update a check in the python wrapper.
