[GitHub] [arrow-rs] tustvold commented on issue #4804: Different encoding options appear to have no effect on output size

   The encoder will always use dictionary encoding by default if enabled, falling back to the specified encoding otherwise. You likely want to disable dictionary encoding for these tests.
   
   As an aside I would probably discourage the delta encoding, the ecosystem support isn't great, and the specification literally links to a paper that says why the particular encoding they chose is a bad idea 😅
