> I think accoding to my reading of https://github.com/apache/parquet-format/blob/master/VariantEncoding.md#value-data-for-object-basic_type2, the field order can vary from objet to object so when comparing two variants for equality the field order should not be taken into account I thought the fields (as in, the field id array) _did_ need to be in (lexical) order? The corresponding value bytes can be out of order but hopefully their physical placement doesn't change the logical equality test. One observation tho -- an unordered metadata dictionary can have duplicate field ids. Two fields have the same name if their field ids are the same, but field ids differing does _NOT_ prove that the fields have different names. -- This is an automated message from the Apache Git Service.
