Description
I see from the source that the TwillRunnerService is locating existing
controllers by querying ZK in the background. Since these run in the
background, there seems to be no way to know when the requests are
complete. Thus, on starting up the service, I can't reliably determine
the complete set of controllers running from previous sessions. Is
there a way to know? Is there a listener I can register?
