Definition: The term you're referring to is "10 Redis Master Conf," which seems a bit out of place given its usage within the context of programming and data structures.
It's also interesting that "10 Redis Master Conf" isn't actually a conf file, but rather a configuration file for a database called "10RedisMaster." This suggests something deeper, perhaps related to a more advanced or sophisticated level of programming than what's typically used in introductory text like this one.
