A cuckoo filter is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set, like a Bloom filter does. False positive matches are possible, but false negatives are not – in other words, a query returns either "possibly in set" or "definitely not in set".

Cuckoo hashing - Wikipedia

In practice, cuckoo hashing is about 20–30% slower than linear probing, which is the fastest of the common approaches. The reason is that cuckoo hashing often causes two cache misses per search, to check the two locations where a key might be stored, while linear probing usually causes only one cache miss per search. However, because of its worst case guarantees on search time, cuckoo hashing can still be valuable when real-time response rates are required.

WebMar 21, 2024 · The main idea is to use a space-efficient probabilistic data structure called Cuckoo filter (CF) [ 4] integrated with an extended node tree (X-tree) [ 5] for many-field packet classification.

WebA quotient filter is a space-efficient probabilistic data structure used to test whether an element is a member of a set (an approximate membership query filter, AMQ).A query will elicit a reply specifying either that the element is definitely not in the set or that the element is probably in the set. The former result is definitive; i.e., the test does not generate false …
