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?
From official Redis
Use hashes when possible
Small hashes are encoded in a very small space
When you haven't to much fields in it.
Every time an hash will exceed the number of elements or element size specified it will be converted into a real hash table, and the memory saving will be lost.
