Broker states are the possible state that a kafka broker can be in. A broker should be only in one state at a time. The expected state transition with the following defined states is:
+-----------+ |Not Running| +-----+-----+ | v +-----+-----+ |Starting +--+ +-----+-----+ | +----+------------+ | +>+RecoveringFrom | v |UncleanShutdown | +----------+ +-----+-----+ +-------+---------+ |RunningAs | |RunningAs | | |Controller+<--->+Broker +<-----------+ +----------+ +-----+-----+ | | | v | +-----+------------+ |-----> |PendingControlled | |Shutdown | +-----+------------+ | v +-----+----------+ |BrokerShutting | |Down | +-----+----------+ | v +-----+-----+ |Not Running| +-----------+
Custom states is also allowed for cases where there are custom kafka states for different scenarios.
