For JSON (one record per file), set the ``multiLine`` parameter to ``true``. If the ``schema`` parameter is not specified, this function goes through the input once to determine the input schema. .. versionadded:: 1.4.0 .. versionchanged:: 3.4.0 Supports Spark Connect. Parameters ---------- path : str, list or :class:`RDD` string represents path to the JSON dataset, or a list of paths, or RDD of Strings storing JSON objects. schema : :class:`pyspark.sql.types.StructType` or str, optional an optional :class:`pyspark.sql.types.StructType` for the input schema or a DDL-formatted string (For example ``col0 INT, col1 DOUBLE``).
