Introduction: In the large data age, there is always the hope that there is a key-value storage mechanism, like hashmap in memory to handle a large number of (tens of millions of orders) of the key-value pairs, in order to improve data lookup, modify speed. So, we'll think of the two NoSQL databases memcached and
