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 available as part of Redis Community Edition and they are available in Redis Software and Redis Cloud. See Install Redis Community Edition or Install Redis Enterprise for full installation instructions.
