We need to teach the rust reader / writer how to also use the Parquet LogicalType **Describe the solution you'd like** The rust writer should write the Variant logical type when writing VariantArrays The rust reader should recognize columns of the Variant logical type and add the relevant arrow extension type metadata **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
