Bloom filters are a way of compactly representing a set of items. It is common to try to compute the size of the intersection or union between two sets. Bloom…

A Bloomfilter is a data structure designed to tell you, rapidly and memory-efficiently, whether an element is present in a set. The price paid for this efficiency is that…

What is Bloom Filter? A Bloomfilter is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set. For example, checking…

Bloom filter basics. The Bloom filter data structure tells whether an element may be in a set, or definitely isn’t. The only possible errors are false positives: a search for…

This is because, although the Bloom filter data does not completely fit into L3 cache, it still gets some benefit from caching. It's easy to see with 'perf stat -d':…

A 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…
