 Bloom filters are used to quickly check whether an element is part of a set.
 Xor and binary fuse filters are a faster and more concise alternative to Bloom filters.
 Furthermore, unlike Bloom filters, xor and binary fuse filters are naturally compressible using standard techniques (gzip, zstd, etc.).
-They are also smaller than cuckoo filters. They are used in production systems such as [databend](https://github.com/datafuselabs/Databend), [ntop](https://github.com/ntop/nDPI), and [InfiniFlow](https://github.com/infiniflow/infinity). The Go xorfilter library is part of [Pebble](https://github.com/cockroachdb/pebble) (Cockroach Labs).
