> Currenty Impala uses the query option "parquet_bloom_filter_write" and table property "parquet.bloom.filter.columns" to decide whether to write bloom filters or not.
> Iceberg uses different table properties: https://iceberg.apache.org/docs/1.4.0/configuration/
> * write.parquet.bloom-filter-enabled.column.col1
> * write.parquet.bloom-filter-max-bytes
> Impala should also respect the Iceberg table properties when it writes Parquet files in Iceberg tables.
