Bloom Filter Definition - Glossary

Bloom Filter is a space-efficient data structure for checking membership in a set with possible false positives.

Bloom Filter is a probabilistic data structure designed to test whether an element is a member of a set. It is highly space-efficient and allows for quick checks. However, it may produce false positives, meaning it might incorrectly indicate that an element is in the set. It achieves its efficiency by using multiple hash functions to map elements to a bit array. Bloom Filters are useful in applications where memory savings are crucial and occasional errors are acceptable, such as in network databases or cache systems.
