> At least for the C export/import, I believe any buffer is allowed to be null if its length would otherwise be zero ( https://arrow.apache.org/docs/format/CDataInterface.html#c.ArrowArray.buffers ), which I think would point to allowing null data buffers in this case. Well, the "empty buffers may be null" rule makes most sense for buffers that are mandatory for the layout. For variadic buffers it is not obvious that null buffers may be useful or desirable. -- This is an automated message from the Apache Git Service.
