rdblue commented on issue #684: Support Decimal in Parquet predicates URL: https://github.com/apache/incubator-iceberg/issues/684#issuecomment-565253385 Iceberg doesn't currently support pushing down predicates because it can't translate from BigDecimal into predicates on Parquet primitives. Parquet stats were also incorrect for decimals stored as Binary, but in that case the stats are suppressed so it is safe to push down the predicates. I think we just need to add the translation for int and long decimal storage, and a comparator for binary decimals.
