Polybase: SQL Server 2019 External File Format - Add First_Row Format Option
In SQL Server 2019 Polybase, for delimited external file formats, the "first_row" format option is not available.
"First_Row = integer -- ONLY AVAILABLE SQL DW"
The first row format option is only available in Azure Synapse Analytics.
This functionality needs to be added into SQL Server 2019 Polybase as well please.
