I just realized that since I am using Pojo cache, I am not sure how Pojo cache creates the FQN when I pass a string id to the PojoCache.attach(String id,Object obj). 

Suppose I pass id as "X/Y" what FQN will be really created?

What will be the performance impact if I have 10-20 variations of "X" and for each X I have 1000,000 variations of "Y"? 

I thought Pojo cache would use X as FQN and Y as the map key when it invokes the core cache, which could be very wrong...

How would I deal with the segmentation of the id strings when I am using Pojo cache for good performance?
