Performance of Redis sets
The Majority of Set operations including finding an element, adding and removing are O(1), i.e constant time-complexity. However, when performing the SMEMBERS command on big sets with hundreds of thousands or more members, you should proceed with caution. This command has an O(n) execution time and returns the complete set in a single response. You can consider the SSCAN, which allows you to iteratively retrieve all members of a set.
