 For example computing slow Set or Sorted set operations and storing them into local keys is an use case for writable slaves that was observed multiple times.
 
-However note that **writable slaves before version 4.0 were uncapable of expiring keys with a time to live set**. This means that if you use `EXPIRE` or other commands that set a maximum TTL for a key, the key will leak, and while you may no longer see it while accessing it with read commands, you will see it in the count of keys and it will still use memory. So in general mixing writable slaves (previous version 4.0) and keys with TTL is going to create issues.
