Sets

Redis Sets have two main differences compared to lists: they are not ordered and they only hold each item once. To create a set, use the command SADD <setkey> <value>. You can use the same command to add more items to the set. For example: SADD names "Flavio" SADD names "Roger" SADD names "Tony" "Mark" "Jane" To retrieve all the items in a set, use the command SMEMBERS <setkey>. You can also use the command SISMEMBER to check if a value is present in the set....
