I've also been experimenting with Bloom filters, and managed to get it
working fairly easily with a nested field:
```
ALTER TABLE glue_catalog.kafka_archive.test_topic
SET TBLPROPERTIES
('write.parquet.bloom-filter-enabled.column.kafka_metadata.key'='true')
```
Then, after downloading a sample data file:
```
$ parquet bloom-filter -c kafka_metadata.key -v foo,4519160c-7d7c-44ae,bar
/tmp/00001.parquet
Row group 0:
--------------------------------------------------------------------------------
value foo NOT exists.
value 4519160c-7d7c-44ae maybe exists.
value bar NOT exists.
```
