RedisBloom - Probabilistic Datatypes Module for Redis

RedisBloom module provides four datatypes, a Scalable Bloom Filter and Cuckoo Filter, a Count-Mins-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.

Command references

Detailed command references for each data structure:

• Bloom Filter
• Cuckoo Filter
• Count-Min Sketch
• Top-K

Bloom vs. Cuckoo

Bloom Filters typically exhibit better performance and scalability when inserting items (so if you're often adding items to your dataset then Bloom may be ideal), whereas Cuckoo Filters are quicker on check operations and also allow deletions.

Client libraries

Each driver comes with its own documentation in the Readme of the driver repo.
