> Currently dynamic min/max/bloom optimization is always enabled. However there
> are times where it may not be beneficial, such as if the semijoin has a PK-FK
> relation and there are no filters on the semijoin table. Try to devise a way
> to do a cost/benefit calculation to see if there is enough benefit to adding
> the runtime filter.
