Performance and Limits of Redis HyperLogLog
Reading from “PFCOUNT” and writing to “PFADD” in the HyperLogLog are performed in O(1) time where as, merging the HyperLogLogs takes O(N) time. The HyperLogLog can estimate the cardianality of sets with up to 264 members.
Complete tutorial on HyperLogLog in redis
Redis HyperLogLog is a powerful probabilistic data structure used for approximating the cardinality of a set. It efficiently estimates the number of unique elements in a large dataset, making it ideal for applications where memory efficiency and speed are crucial. In this article, we will explore what Redis HyperLogLog is, its syntax, and commands, and provide examples of how to use it in real-world scenarios.
