What is the maximum number of masters that should be in the system?

In Go (Golang), the term "master" is not a standard concept of the language, so the maximum number of masters depends on the context of the specific system or architecture in which this term is used.

For example, if we are talking about the master-worker pattern, the number of masters is usually limited to one or a few instances to coordinate the work of workers. The maximum number of masters is determined by the system's requirements for fault tolerance and scalability.

In general, Go does not have a built-in limit on the number of "masters" — it depends on the application's architecture and business logic. If a more precise number is needed, the context of the use of the "master" term should be clarified.
