# @redis/bloom This package provides support for the [RedisBloom](https://redisbloom.io) module, which adds additional probabilistic data structures to Redis. It extends the [Node Redis client](https://github.com/redis/node-redis) to include functions for each of the RediBloom commands. To use these extra commands, your Redis server must have the RedisBloom module installed. RedisBloom provides the following probabilistic data structures: * Bloom Filter: for checking set membership with a high degree of certainty. * Cuckoo Filter: for checking set membership with a high degree of certainty. * Count-Min Sketch: Determine the frequency of events in a stream. * Top-K: Maintain a list of k most frequently seen items. For complete examples, see `bloom-filter.js`, `cuckoo-filter.js`, `count-min-sketch.js` and `topk.js` in the Node Redis examples folder.
