Redis 4.x Cookbook

Using the sorted set data type

Compared to the data type set introduced in the previous recipe, sorted list is a similar but more complex one in Redis.

It's convenient to take advantage of this natively sorted feature in some scenarios for which the sorting is needed all the time. In this recipe, we'll see how to manipulate sorted set.
