Redis Data Type--hash

A Redis hash value is a mapping between a string field and a string value

It provides many convenient domain operations compared to data types such as String, so it is a very good data type when it comes to representing objects.

The hash value storage capacity in Redis is very large and can store more than 4 billion key value pairs

Consider the hash type in Redis as a map container with string key and string value. Therefore, this type is ideal for storing information about value objects. such as username, password, and age

Hash is a mapping table of some column key value (field value). It is often used to store some object instances. Storing as a hash consumes less memory than storing the individual fields of an object as a string. Why do you save more memory? You need to figure out what the two configurations (Hash-max-zipmap-entries and Hash-max-zipmap-value) mean.

In Redis, use the Hset command to set the value of the field field in the hash table key to
