Are you talking about Cuckoo++ tables, perhaps? If not can you point me to the hash table you had in mind? Always fun to learn of a new approach.

IIRC, it's this paper: https://db.in.tum.de/~birler/papers/hashtable.pdf

I never implemented their hash table, but it opened my eyes to the technique of a tiny Bloom filter, which I've used now a couple of times to fairly good (if small) effect. :-)

Thanks! This'll be a fun read :)
