Memcache is mainly designed to relieve database pressure and speed up, so it is a stateless data (stateless data: the current data is not bound to a user, such as Lee stored data, richard can obtain the corresponding key value)
Session data is bound to users, so it is stateful data.

Suitable for storing data in Memcached
Frequent and unstable changes, without the need to store data in real time, with low security
