> a)  For 200K segments table in cloud, presto partition query was taking more than 5 hours. the reason is it was reading all segment files for partition pruning. Now it is less than a minute !
>  
> b) If the query filter is less than or greater than or more than one value. Partition pruning is not working in presto (due to missing code in presto-carbon integration)
