dongxiaoman opened a new issue #6626:
URL: https://github.com/apache/incubator-pinot/issues/6626


   Right now if we write something like `SELECT  * FROM fact WHERE 
primary_key_id in ('id1', 'id2', 'id3', .....'id10' ) and created_at in (ts1, 
ts2, ts3, ts4, ... ts10) LIMIT 2000` it is actually running slower than not 
passing in `created_at in (xxx....)` filter.
   But if we convert the `created_at in (xxx) ` into a range filter, it will 
run faster. Converted query is like below
    
   `SELECT  * FROM fact WHERE primary_key_id in ('id1', 'id2', 'id3', 
.....'id10' ) and created_at <= 1614426347 and created_at >= 1614426293 LIMIT 
2000`
