builder

public static CsvReadOptions.Builder builder(InputStream stream)

This method may cause tablesaw to buffer the entire InputStream.

If you have a large amount of data, you can do one of the following: 1. Use the method taking a File instead of a stream, or 2. Provide the array of column types as an option. If you provide the columnType array, we skip type detection and can avoid reading the entire file
