Because of this semantic MSETNX can be used in order to set different keys representing different fields of a unique logic object in a way that ensures that either all the fields or none at all are set. According to the cuckoo filter behavior, the filter is likely to declare itself full before capacity is reached; therefore, the fill rate will likely never reach 100 percent.
