WebAbout. A cuckoo is a summer visitor to Britain, arriving from Africa in late March and April. They are famous for laying their eggs in other birds’ nests, fooling them into raising their … 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". A cuckoo filter … See more A cuckoo filter uses a $${\displaystyle n}$$-way set-associative hash table based on cuckoo hashing to store the fingerprints of all items (every bucket of the hashtable can store up to $${\displaystyle n}$$ entries). … See more • Probabilistic Filters By Example – A tutorial comparing Cuckoo and Bloom filters. See more • A cuckoo filter can only delete items that are known to be inserted before. • Insertion can fail and rehashing is required like other cuckoo hash tables.

WebCuckoo hashing is a form of open addressingin which each non-empty cell of a hash tablecontains a keyor key–value pair. A hash functionis used to determine the location for each key, and its presence in the table (or the value associated with it) can be found by examining that cell of the table. WebSep 21, 2024 · The Cuckoo filter is a compact variant of a Cuckoo hash table that stores only fingerprints (hash) of the data, instead of key/value pairs. The size of the fingerprint …
WebMay 22, 2024 · Support Optimality and Adaptive Cuckoo Filters. Filters (such as Bloom Filters) are data structures that speed up network routing and measurement operations by storing a compressed representation of a set. Filters are space efficient, but can make bounded one-sided errors: with tunable probability epsilon, they may report that a query … WebA 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.

WebCuckoo filters support adding and removing items dynamically while achieving even higher performance than Bloom filters. For applications that store many items and target moderately low false positive rates, cuckoo filters have lower space overhead than space-optimized Bloom filters.

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.
