Additional context

It's possible for ParquetSharp to check the data sort, but I feel it's not necessary.

Hi @alxu-avpt, yes we should add this to ParquetSharp. Is this something you could make a PR to add?

I agree it's not necessary to check the sort order, we should just document that it's up to the user to ensure their sort order is correct.
