[jira] [Created] (ARROW-6643) [C#] Write no IPC buffer metadata for NullType

Eric Erhardt created ARROW-6643:
-----------------------------------

             Summary: [C#] Write no IPC buffer metadata for NullType
                 Key: ARROW-6643
                 URL: https://issues.apache.org/jira/browse/ARROW-6643
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C#
            Reporter: Eric Erhardt


We need to align the C# writer (and test the reader) for NullType. See [https://github.com/apache/arrow/pull/5287] and ARROW-6379.

 

>The C++ implementation has been writing 2 {{Buffer}} Flatbuffer struct values with length 0 for NullType. Rather than having dummy/placeholder Buffer I think it is more consistent to write no metadata for this type.
