mslevine opened a new issue, #35718:
URL: https://github.com/apache/arrow/issues/35718
### Describe the bug, including details regarding any error messages,
version, and platform.
The writer panics if DeltaBinaryPacked encoding is requested for a column
that is all null. The following small change to an existing test case
demonstrates the issue.
In case it matters, I'm using `go version go1.20.4 darwin/amd64`
I ran into this issue using arrow v12.0.0, but this changed testcase fails
using the current head of main.
