Redis 4.x Cookbook

How to do it…

The steps for using SORT are as follows:

1. Open a Terminal and connect to Redis with redis-cli.
2. If all elements are numeric, we can simply run the SORT key to sort the elements in ascending order. Suppose in Relp we store a user's favorite restaurant IDs in a Redis set:

127.0.0.1:6379> SADD "user:123:favorite_restaurant_ids" 200 365 104 455 333(integer) 5127.0.0.1:6379> SORT "user:123:favorite_restaurant_ids"1) "104"2) "200"3) "333"4) "365"5) "455"

3. If there are non-numeric elements and we want to sort them by lexicographical order, we need to add the ALPHA modifier. Suppose we store restaurant names in the set:

 127.0.0.1:6379> SADD "user:123:favorite_restaurants" "Dunkin Donuts" "Subway" "KFC" "Burger King" "Wendy's" (integer) ...
