Randall O'Reilly created ARROW-4387:
---------------------------------------
Summary: [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.
