json - Storing object properties in redis

Question

Lets say I have an object (User) which consists of a few properties (ID, Name, Surename, Age). Which way is better to store this object in redis?

• store each property value in dedicated key, for example user:{id}:id, user:{id}:name, user:{id}:surename, user:{id}:age
• store whole User object as JSON string in one key, for example user:{id}:json (value of the key will be something like this: {"ID": 123, "Name": "Johny", "Surename": "Bravo", "Age": 22})

Answer 1

According to these two sources probably the optimal solution would be to use hashes because of memory consumption when using dedicated keys and long string in scenario with JSON as key value.
