Description

Currently, I am using CSV data source and trying to get used to Spark 2.0 because it has built-in CSV data source.

I realized that CSV data source infers schema with all the data. JSON data source supports sampling ratio option.

It would be great if CSV data source has this option too (or is this supported already?).
