Hi @fraugster @akrennmair @panamafrancis,

I would like to know how to read the following schema with parquet-go?

message spark_schema {
  optional group foo (LIST) {
    repeated group list {
      optional double element;
    }
  }
  required group bar (LIST) {
    repeated group list {
      required double element;
    }
  }
}

the following seems not to work:

type Record struct {
	Foo FooList `parquet:"foo.list"`
	Bar   BarList   `parquet:"bar.list"`
}

type FooList struct {
	List []FooListList `parquet:"list"`
}

type FooListList struct {
	List []float64 `parquet:"element"`
}

type BarList struct {
	List BidValuesListList `parquet:"list"`
}

type BarListList struct {
	List []float64 `parquet:"element"`
}

while this works fine with github.com/segmentio/parquet-go lib:

type Record struct {
	Foo BarList `parquet:"foo"`
	Bar   BarList   `parquet:"bar"`
}

type FooList struct {
	List []FooListList `parquet:"list"`
}

type FooListList struct {
	List []float64 `parquet:"element"`
}

type BarList struct {
	List BarListList `parquet:"list"`
}

type BarListList struct {
	List []float64 `parquet:"element"`
}
