Bloom Filters by Example
Bloom Filters by Example A Bloom filter 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 a Bloom filter is a probabilistic data structure: it tells us that the element either definitely is not in the set or may be in the set. The base data structure of a Bloom filter is a Bit Vector. Here's a small one we'll use to demonstrate: Each empty cell in that table represents a bit, and the nu
