Redis SMISMEMBER Command Explained

Redis SINTERCARD Command Explained
In Redis, the SINTERCARD command returns the cardinality of the set which would result from the intersection of all the given sets. It’s similar to SINTER, but instead of returning the result set, it returns just the cardinality of the result.
The SINTERCARD command was introduced in Redis 7.0.0.
Redis SINTERSTORE Command Explained
In Redis, the SINTERSTORE command is the same as the SINTER command, except that it stores the result in the specified key, instead of returning it.
It stores the members of the set resulting from the intersection of all the given sets.
If the destination key already exists, it’s overwritten. If it doesn’t exist, it’s created and the resulting members are added to it.

In Redis, the SINTER command returns the members of the set resulting from the intersection of all the given sets.
Redis SDIFFSTORE Command Explained
In Redis, the SDIFFSTORE command works just like the SDIFF command, except that instead of returning the result, it stores it in the key that we specify. The destination key will then hold the members of the set resulting from the difference between the first set and all the successive sets.
Redis SDIFF Command Explained
In Redis, the SDIFF command returns the members of the set resulting from the difference between the first set and all the successive sets. In other words, it returns all members of the first set that aren’t in any of the successive sets.
Redis SCARD Command Explained
