Hi @domyway, you can check whether bloom filter works by
`row_groups_pruned_bloom_filter` metric now.
In my environment, bloom filter works.
```
❯ CREATE EXTERNAL TABLE taxi
STORED AS PARQUET
LOCATION
'/home/deepin/rust/arrow-datafusion/parquet-testing/data/data_index_bloom_encoding_stats.parquet'
;
0 rows in set. Query took 0.002 seconds.
❯ SET datafusion.execution.parquet.bloom_filter_enabled to true;
0 rows in set. Query took 0.001 seconds.
❯ EXPLAIN ANALYZE SELECT * FROM taxi WHERE (taxi."String" IN ('bb', 'bbc',
'bba', 'bbd', 'bbg', 'bbf', 'bbn', 'nnfa', 'bbnfd', 'bbx', 'bbxda', 'badfas',
'afd', 'adfas', 'adfa', 'asdfer', 'sefarj', 'erseioio', 'uioosdf', '0ba24'));
....row_groups_pruned_bloom_filter=1, .....
```
Thank you for finding it.
