9 years ago A filter construction described in a 2014 paper [1] allows for removal. The Cuckoo Filter is an alternative to a Bloom Filter that leverages partial key cuckoo hashing and a fingerprint/bucket structure.
@beala and I have proposed the addition of a Cuckoo Filter to Guava in #2226. We have a working implementation that we could adapt to the Guava style fairly if there's interest.

In a paper from 2005[1], Pagh et al. proposed a bloom filter extension that is also capable of removing elements. Getting the number of items stored within is also possible through this extension. Do you see any possibility to extend Guava to also support these features?
