Antoine Pitrou commented on ARROW-1774:
---------------------------------------
What is meant here by "same physical memory layout"? For example, should we
allow a view of int32 as float32? If so, it's not the same thing as casting.
> [C++] Add "view" function to create zero-copy views for compatible types, if
> supported

> URL: https://issues.apache.org/jira/browse/ARROW-1774
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Wes McKinney
> Priority: Major
> Fix For: 0.14.0
>
>
> Similar to NumPy's {{ndarray.view}}, but with the restriction that the input
> and output types have the same physical Arrow memory layout. This might be as
> simple as adding a "zero copy only" option to the existing {{Cast}} kernel
