Redis Core Data Structures Mastery Hub: The Industry Foundat

In the context of Redis Strings, which of the following commands is the most efficient for atomically incrementing a counter by a specific value greater than 1, while also returning the *new* value?

When dealing with large string values in Redis, what is the primary advantage of using `GETRANGE` over fetching the entire string with `GET` and then processing it client-side?

Consider a scenario where you have a Redis String key `user:123:last_login` storing a Unix timestamp. You want to increment this timestamp by 60 seconds to represent a delayed login event, *but only if the current timestamp is older than the one stored*. Which combination of Redis commands best achieves this atomically?
