Hi, I was exploring the apache arrow code and saw this this <https://github.com/apache/arrow/blob/b655852b260d3b8c3fe457795df0f42a2ff9c98c/cpp/src/arrow/util/bpacking64_default.h#L35C1-L40C2> in the repo. What does it mean when bit width is zero in dictionary encoded files? What is the scenario where data will be encoded with bit width zero and how could such a file be generated?
Regards, Marko
