LeaderRole

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ZeebeLogAppender

A log appender provides a central entry point to append to the local Raft log such that it is automatically replicated and eventually committed, and the ability for callers to be notified of various events, e.g. ZeebeLogAppender.AppendListener.onCommit(IndexedRaftLogEntry).
