+# @redis/bloom
+
+This package provides support for the [RedisBloom](https://redis.io/docs/data-types/probabilistic/) module, which adds additional probabilistic data structures to Redis.
+
+Should be used with [`redis`/`@redis/client`](https://github.com/redis/node-redis).
+
+:warning: 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.
+* T-Digest: for estimating the quantiles of a stream of data.
+* Top-K: Maintain a list of k most frequently seen items.
+* Count-Min Sketch: Determine the frequency of events in a stream.
+
+For some examples, see [`bloom-filter.js`](https://github.com/redis/node-redis/tree/master/examples/bloom-filter.js), [`cuckoo-filter.js`](https://github.com/redis/node-redis/tree/master/examples/cuckoo-filter.js), [`count-min-sketch.js`](https://github.com/redis/node-redis/tree/master/examples/count-min-sketch.js) and [`topk.js`](https://github.com/redis/node-redis/tree/master/examples/topk.js) in the [examples folder](https://github.com/redis/node-redis/tree/master/examples).
