> [Go] tensor doesn't support access to Null bitmap data?
> -------------------------------------------------------

>                 Key: ARROW-4387
>                 URL: https://issues.apache.org/jira/browse/ARROW-4387
>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: Go
>    Affects Versions: 0.12.0
>         Environment: n/a
>            Reporter: Randall O'Reilly

> It seems that the tensor interface does not provide access to the Null bitmap 
> data in the underlying array. The root cause appears to be that Data does not 
> have the null bitmap data and associated IsNull / IsValid methods, and tensor 
> only retains the Data and not the Array -- only the array has the actual null 
> bitmap and associated methods. So either keeping the array.Interface around 
> or moving the null bitmap into Data would seem to be the necessary steps.
