Probabilistic

Probabilistic data structures in Redis

Probabilistic data structures give approximations of statistics such as counts, frequencies, and rankings rather than precise values. The advantage of using approximations is that they are adequate for many common purposes but are much more efficient to calculate. They sometimes have other advantages too, such as obfuscating times, locations, and other sensitive data.

Probabilistic data structures are not available by default in the basic Redis server, so you should install Redis Stack or Redis Enterprise, both of which include probabilistic structures and other useful modules. See Install Redis Stack or Install Redis Enterprise for full installation instructions.
