GitHub user willtemperley added a comment to the discussion: Why does the Parquet encoding list show both 'PLAIN' and 'BIT_PACKED'? Is BIT_PACKED actually used?
I was looking into this a bit and I'm fairly sure parquet-java 1.15.1 is writing def levels as BIT_PACKED by default. The attached file is a small test file I created with this version to confirm. I haven't inspected it at the byte level yet though.
