> Where is this in the Parquet spec? I cannot find a [similar example](https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#lists). The wording of the spec is very ambigious: > If the repeated field is not a group, then its type is the element type and elements are required. If the repeated field is a group with multiple fields, then its type is the element type and elements are required. If the repeated field is a group with one field and is named either array or uses the LIST-annotated group's name with _tuple appended then the repeated type is the element type and elements are required. Otherwise, the repeated field's type is the element type with the repeated field's repetition. I think this just following the rule(1): the repeated field is not a group, then its type is the element type and elements are required. -- This is an automated message from the Apache Git Service.
