[jira] [Comment Edited] (ARROW-2667) [C++/Python] Add pandas-like take method to Array

    [ https://issues.apache.org/jira/browse/ARROW-2667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16856516#comment-16856516 ]

----------------------------------------------------------------------

[~wesmckinn] you renamed this issue to only be about Array (and opened ARROW-5454 for the ChunkedArray part). So then this can be closed? (the python Array part was tackled in ARROW-5291)

Edit: the other issue is only about C++, so we can keep this open for the Python side of course.

> We should add a {{take}} method to {{Array/ChunkedArray/Column}} that takes a list of indices and returns a reordered array.
