Redis caches only all key information, and if the memory usage exceeds a certain threshold, the operation that will trigger the swap will persist the value corresponding to some key to disk and be purged in memory. This feature allows Redis to maintain data that is larger than the memory size of its machine itself. When reading data from Redis, if the value of the read key is not in memory, then Redis need

The specific method is to encrypt the user password into the hash function, and
