> Four new types were added to the Parquet Variant spec ([https://github.com/apache/parquet-format/commit/25f05e73d8cd7f5c83532ce51cb4f4de8ba5f2a2):] UUID, Time, Timestamp(NANOS) and TimestampNTZ(NANOS).
> Spark does not have corresponding types, but we should add support for basic Variant operations: extraction, cast to JSON/string, and reporting the type in SchemaOfVariant.
