Xor Filters: Faster and Smaller Than Bloom Filters
They praise bloom filters for being simple and describe how it works in two sentences. They criticize cuckoo filters for being too complicated. They praise their own algorithm for being simple, and then they don't describe it, and instead link to a repo of several hundred lines of code.My guess is it's one of those things that are simple to understand for the guy that wrote it but inscrutable for everyone else. I'm not ashamed to admit that I have several such code blobs in production right now, but I won't pretend to call them simple.
