   @adriangb Good suggestion! Reusing TPC-H data with multiple parts and 
renaming is much simpler. Plan:
   
   1. Generate TPC-H with `--parts=3` (files have non-overlapping l_orderkey 
ranges)
   2. Rename files so alphabetical order is reversed vs key order (e.g., part 
with highest keys → `a_xxx`, lowest → `c_xxx`)
   3. Benchmark uses `--sorted` to declare `WITH ORDER`
   
   No need for datafusion-cli or SQL splitting. Working on it.
