This draft PR demonstrates what a future Parquet V3 version table could look like, stacked on apache#186.

If we went with a real version 3 it would be represented like this:

Changes:

  • Adds a V3 column to the backwards incompatible feature table.
  • Marks existing V1/V2 features as available in V3.
  • Adds not-yet-released example V3 rows for ALP, FSST, FastLanes integer encoding, and removing path_in_schema.
