> Impala supports 'decimal' type in AVRO. 'Decimal' is a logical type, that can annotate either 'bytes' or 'fixed' type underneath. Impala can read 'bytes' but not 'fixed'.
> Iceberg writes 'decimal' type with underlying 'fixed' type. This means that Impala is currently unable to support 'decimal' in AVRO tables written by Iceberg. In order to fully support all implementations of 'decimal', 'fixed' type must be supported.
