Redis SADD – How to create and add elements in the set

In this tutorial, we will learn about how to create and add elements in a set value stored at the key, by using a COMMAND – SADD in redis-cli. If a key exists in the datastore, all the specified elements will be added (ignoring the elements that are already present ) to the set otherwise a new set will be created before adding them to set. The syntax of redis SADD command is as follows :-

Syntax :-

redis host:post> SADD <key name> <value 1> [ <value 2> ]

Output :- 

- (integer value), representing the number of elements added to the set, not including all the elements
  that were already present.
