Class LeaderChecker

  • public class LeaderChecker
    extends java.lang.Object
    The LeaderChecker is responsible for allowing followers to check that the currently elected leader is still connected and healthy. We are fairly lenient, possibly allowing multiple checks to fail before considering the leader to be faulty, to allow for the leader to temporarily stand down on occasion, e.g. if it needs to move to a higher term. On deciding that the leader has failed a follower will become a candidate and attempt to become a leader itself.
