WebQuotient filters and cuckoo filters use a similar amount of memory. •Morton filters[8] are similar to cuckoo filters, but use underloaded buckets, like Horton tables [9]. Many sparse buckets are combined into a block so that data is stored more densely. •Bloomier filters[12, 13] support approximate evaluation of arbitrary functions, in ... 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 …

WebA Bloom filter is a space-efficient probabilistic data structure, conceived by Burton Howard Bloom in 1970, that is used to test whether an element is a member of a set. 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". 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. False positive matches are …
WebApplying partial-key cuckoo hashing—a variant of stan-dard cuckoo hashing—to build cuckoo filters that sup-port dynamic addition and deletion of items (Section3). Exploring the reason why partial-key cuckoo hashing ensures high table occupancy for most real-world appli-cations (Section4). Optimizing cuckoo filters to outperform Bloom ... WebCuckoo filters are based on cuckoo hashing. A Cuckoo filter is essentially a cuckoo hash table which stores each key's fingerprint. As Cuckoo hash tables are highly compact, a cuckoo filter often requires less space than conventional Bloom filters for applications that require low false positive rates (< 3%).

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. Our choice of X-tree came from that the X-tree has high query performance.
