What is the method for serializing objects in Redis?

Redis offers two ways to serialize objects: 1. Redis Object Hashing (ROH): Redis can serialize objects into binary data and store them as Redis strings. This method allows objects to be stored and retrieved using Redis data structures and methods. For example, using the HASH type can map the attributes of an object to fields in a Redis hash table. 2. Redis Serialization Protocol (RESP): RESP is a protocol used to serialize data, supporting the serialization and deserialization of multiple data types. By serializing objects into RESP format data, they can be stored as Redis strings or other data structures. This method requires manual serialization and deserialization, which can be implemented using serialization libraries provided by Redis (such as redis-py). It is important to note that data stored in Redis after serialization is not readable, so corresponding deserialization operations are necessary when retrieving objects. Additionally, the serialization and deserialization process may introduce some performance overhead, so it is important to consider data access frequency and performance requirements when choosing a serialization method.
