For clarity and maintainability, it is often recommended to develop a system or schema for naming your Redis keys. Here are some examples of common and maintainable systems for naming your keys:
user:10134
user:10134:favorites
user:10134:friends
user:10134:friends-of-friends
user:10134
user:10134/favorites
user:10134/friends
user:10134/friends.of.friends
user/10134
user/10134/favorites
user/10134/friends
user/10134/friends of friends
Note that, while allowed, larger keys use more memory and result in slower lookup times, so using a 500MB key might not be a great idea for performance. A better idea might be to use a SHA-1, SHA-256, or MD5 hash of a large binary object as a key instead:
