Hi,

How can I read the entire data into a slice call Foo? Is there a better option than for loop with fr.Next() as you do it here https://github.com/fraugster/parquet-go/blob/master/examples/read-low-level/main.go#L44?

type Foo struct {
	Id						int64	`parquet:"name=id, type=INT64"`
	StartDate				int64	`parquet:"name=start_date, type=BYTE_ARRAY"`
	EndDate					int64	`parquet:"name=end_date, type=BYTE_ARRAY"`
}

fr, err := NewFileReaderWithOptions(bytes.NewReader(content))
u := make([]*Foo, fr.NumRows())

The text was updated successfully, but these errors were encountered:
