For those commands supported by cluster mode, they are atomic. However, some commands are limited supported by cluster mode, e.g. commands that take multiple keys. For example, you can run SADD atomically in cluster mode, but you cannot run SUNION, unless all keys are mapped to the same hash slot. Also hash tag can help us map keys to the same slot.
