builder

public static JsonReadOptions.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

builder

public static JsonReadOptions.Builder builder(Reader reader)
