> It is part of work for Flip-6.
> The {{HeartbeatManager}} is mainly used for monitoring heartbeat target and
> reporting payloads.
> For {{ResourceManager}} side, it would trigger monitoring the
> {{HeartbeatTarget}} when receive registration from {{TaskManager}}, and
> schedule a task to {{requestHeartbeat}} at interval time. If not receive
> heartbeat response within duration time, the {{HeartbeatListener}} will
> notify heartbeat timeout, then the {{ResourceManager}} should remove the
> internal registered {{TaskManager}}.
> For {{TaskManger}} side, it would trigger monitoring the {{HeartbeatTarget}}
> when receive registration acknowledgement from {{ResourceManager}}. An it
> will also be notified heartbeat timeout if not receive heartbeat request from
> {{ResourceManager}} within duration time.
> The current implementation will not interact payloads via heartbeat, and it
> can be added if needed future.
