  3. new SparkToParquetSchemaConverter(writeLegacyParquetFormat: Boolean = ..., outputTimestampType: internal.SQLConf.ParquetOutputTimestampType.Value = ...)

    writeLegacyParquetFormat

    Whether to use legacy Parquet format compatible with Spark 1.4 and prior versions when converting a Catalyst StructType to a Parquet MessageType. When set to false, use standard format defined in parquet-format spec. This argument only affects Parquet write path.

    outputTimestampType

    which parquet timestamp type to use when writing.
