Subject [jira] [Commented] (ARROW-33) C++: Implement zero-copy array slicing
Date Mon, 19 Dec 2016 23:50:58 GMT


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.
