[jira] [Commented] (ARROW-33) C++: Implement zero-copy array slicing

["Wes McKinney (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-33?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15762678#comment-15762678 ] 

Wes McKinney commented on ARROW-33:
-----------------------------------

From a strictly C++ implementation perspective, the most robust way to support array slicing will be to add an {{offset}} member to the base Array class. Otherwise, the bitmap must be copied. [~xhochy] what do you think about this? This is most likely what we'll end up doing in pandas 2.0, for example.
