WebRedis SINTER command gets the elements of a set after intersection of all specified sets. Keys that do not exist are considered to be empty sets. With one of the keys being an empty set, the resulting set is also empty (since set intersection with an empty set always results in an empty set). Return Value WebRedis has commands to test for membership. For example, checking if an element exists: > sismember myset 3 (integer) 1 > sismember myset 30 (integer) 0 "3" is a member of the set, while "30" is not. Sets are good for expressing relations between objects. For instance we can easily use sets in order to implement tags.

Web25. apr 2024 · Everytime I push something to the set, I also include an empty/dummy object, so this way, if I remove all the valid data from that key, Redis will still keep it, because the dummy object would remain. Then, everytime the app needs to read the data, then it adds an extra step to remove that dummy object. WebWith a Redis Set, adding a new member and checking whether a member is in the Set are both O (1) operations, meaning their performance doesn't degrade as the Set grows. However, every new member of a Set that we add (in our case these are unique checkins) causes the Set to take up more memory on the Redis server.
