    en.wikipedia.org/wiki/Approximate_Membership...

    The AMQ filter functions as a proxy to the set of keys of a database or remote memory. Before a presumably slow query to the database or to remote memory is performed, the AMQ filter is used to give an approximate answer as to whether the key is in the database or in remote memory. The slow query is only performed when the AMQ filter returns true.
