RedisBloom module provides four datatypes, a Scalable Bloom Filter and Cuckoo Filter, a Count-Min-Sketch and a Top-K. Bloom and Cuckoo filters are used to determine (with a given degree of certainty) whether an item is present or absent from a collection. While Count-Min Sketch is used to approximate count of items in sub-linear space and Top-K maintains a list of K most frequent items.
Note: You can also build and load the module yourself.
docker run -p 6379:6379 --name redis-redisbloom redislabs/rebloom:latest
docker exec -it redis-redisbloom bash
# redis-cli
# 127.0.0.1:6379>
Start a new bloom filter by adding a new item
# 127.0.0.1:6379> BF.ADD newFilter foo
(integer) 1
Checking if an item exists in the filter
# 127.0.0.1:6379> BF.EXISTS newFilter foo
(integer) 1
In order to use this module, build it using make and load it into Redis.
