Hi, I'm not very familiar with parquet-mr which your example appears to be based on, nor am I hugely knowledgeable about the record APIs for reading parquet, but I'll try to help out here 😅 Perusing the docs it would appear you can use https://docs.rs/parquet/latest/parquet/file/reader/trait.FileReader.html#tymethod.get_row_iter to get a row iterator, and then call https://docs.rs/parquet/latest/parquet/record/trait.RowAccessor.html#tymethod.get_list on the row. FWIW I would strongly encourage you to consider trying out the arrow interface, it should be faster, better tested and better documented than the record APIs which are somewhat orphaned at the moment... -- This is an automated message from the Apache Git Service.
