> a lot of segment files will be generated after a few hours
>  when i try to use presto to query.
>  single condition can be queried, but cannot be queried when there are multiple conditions.
> select name from test_table // ok
>  select name from test_table where name = 'joe' // ok
>  select name from test_table where name='joe' AND age > 25;// query failed
>  select name from test_table where name='joe' AND age > 25 AND city ='shenzhen';// query failed
> i have also tried to compact 'major' the segment files to reduce the segment quantity, and I still cannot query successfully.
