Redis Set Command

Remove one or more items/members from a set. If the member is not present in the set, then then it is ignored. If the does not exist, then it is treated like an empty set.

Get all the members of a set. We get the full list of all the members. This is the only proper command available to get items/members from a set.

Add one or more items/members to a set. Multiple member elements are supported in the command. So we can add one or more members to the same set at the same time. If the key does not exist, then it is created and then members are added to it. If the item/member element already exists in the set, then it is ignored.
