As the title says, I want to create a ristretto cache instance which can keep track of n key value pairs of 1 cost.

Hi @helloworld,
welcome to the community. Does something like this not work?

cache := ristretto.NewCache(&ristretto.Config{MaxCost:1, NumCounters:n*10}}

@chewxy Thanks for the suggestion. Although I have tried that but it is not working as expected. Set is successful but Get is not able to retrieve the value. I am waiting for 100 ms before calling after Set but still Get is failing. If I set NumCounters to >=500(50*10) then Get is working as expected.
