> Currently, global bloom index will check inputs against files in all partitions.. In
lot of cases, the user may know a range of partitions actually impacted from updates clearly
(e.g upstream system drops updates older than a year, ... )..  In such a scenario,it may make
sense to support an option for Global bloom to control how many partitions you want to match
against, to gain performance.
