Detects exited workers through a lapsed heartbeat. This differs
from rrq_worker_list_exited() which lists workers that have
definitely exited by checking to see if any worker that runs a
heartbeat process has not reported back in time, then marks that
worker as exited. See vignette("fault-tolerance") for details.
Arguments
- controller
The controller to use. If not given (or
NULL) we'll use the controller registered withrrq_default_controller_set().
Examples
if (FALSE) { # rrq:::enable_examples(require_queue = "rrq:example")
obj <- rrq_controller("rrq:example")
rrq_worker_detect_exited(controller = obj)
}
