Just so nobody is confused, HyperLogLog etc. are used for a different operation than Bloom/Cuckoo filters. HLL is used to determine how many unique items you have, the cardinality of a set. Bloom/Cuckoo is used to determine set membership, as in "have I seen this item before". Not sure how much that helps but the distinction was lost on me when I started reading about them. |
