is this a bit optimistic? I don't know how datafusion sort operators treat this but would we want to fallback to a near sorted optimised sort strategy always if we have an ascending sort of a column that exists in the file?

ordered here is just "the order of the file", instead of returning batches in whichever order we get them.

ah I mean returning Inexact instead of Unknown here because we only know that the column exists at this point, and not much about how it is sorted

you're right, I've simplified it for now.

@joseph-isaacs we do (some of the top-k style queries), but I'm not sure we have a benchmarks with a sorted table in the way DF can understand. |

Summary
Naive implementation of
try_pushdown_sort, its mostly just parts of the parquet impl + making sure we propagate the information into the Vortex scan.
