[GitHub] [arrow-datafusion] crepererum commented on issue #4169: Add ability to specify external sort information for ParquetExec

   One alternative would be to encode the "sorted by" property into the parquet file itself. Sure that's more effort, but I kinda think that it would be nicer for the ecosystem. This metadata would be optional and solely help optimization (although if specified, it must be correct). This is very similar to statistics.
