In this tutorial, we will learn about how to get the size ( number of elements ) of a sorted set value stored at the key, by using a COMMAND – ZCARD in redis-cli. The syntax of redis ZCARD command is as follows :-
redis host:post> ZCARD <key name>
(integer) value, representing the number of elements in the sorted set. (integer) 0, if key does not exist. Error, if key exist and value stored at the key is not a sorted set.
