Ordering should be defined at the logical type level, not physical type. > If we agree that FLBA(16) is better repr for an integer of 128 bits > (through logical type annotation) would this mean we should consider > deprecating INT32/INT64/FLOAT/DOUBLE in favor of FBLA(4)/FBLA(8) with > logical types? It depends what "deprecating" entails. We do not want to disrupt the ecosystem needlessly. But if we were designing a new Parquet format from scratch, I would definitely advocate for a reduced set of 3 physical types: BIT, FLBA and VLBA. Regards Antoine.
