This PR adds a new topology type called
initializerwhich is a building block forleader. The initializer topology performs a leader election without leader fallback.Also new in this PR is the
inithook. The contents of the hook are run during an initialization step prior to the run hook. When this hook runs depends on the topology chosen, but it is always before the run hook. When your service is running in theleaderoriniitalizertopology the hook is run first by the master and then, after the master has run it's hook, the followers will run their initialization.The hook can be parameterized to know if the leader or the follower is running the hook by checking
{{census.me.leader}}.The original leader topology's behaviour is unchanged with the exception of it now performing service initialization as described above.
