WebMay 15, 2009 · A bloom filter is for when you have limited space, high query cost, and mostly negative queries. In that case, a bloom filter with 8 bits per key and 4 hash functions gives you 2.5% false positive rate; you process queries nearly 40 times faster than before, at the cost of 1 byte per key. WebBloom Filters are one of a class of probabilistic data structures. The Bloom Filter uses hashes and probability to determine whether a particular item is present in a set. It can do so in constant time: O (1) and sub-linear space, though technically still O (n).

WebBloom filters are designed for situations where a false negative is a Very Bad Thing and a false positive is acceptable. For example, suppose that you are making a web browser and have a known blacklist of scam websites. Your blacklist is massive - in the hundreds of gigabytes - so you can't ship it with the browser.
