First time throwing up an issue here so let me know if there's anything I missed / more details I can provide.
Just going through the arrow documentation at https://arrow.apache.org/docs/python/ and I noticed that there's a section that is currently blank. From what I can tell the section https://arrow.apache.org/docs/format/Metadata.html#dictionary-encoding currently contains nothing in it. Is that intended? It was confusing to see a blank section, but that is just my opinion so it may not be worth changing.
If this is something work fixing / improving, then it's probably worth either filling out that section or simply removing header to avoid future confusion.
