> {{CataystConverter}} classes are used to convert Parquet records to Spark SQL row objects. Current converter implementations have the following problems:
> # They simply ignore original Parquet schema, which makes adding Parquet backwards-compatibility rules impossible.
> # They are unnecessary over complicated.
> # {{SpecificMutableRow}} is only used for structs whose fields are all of primitive types.
