Returns the task id that each worker is working on, if any.
rrq_worker_task_id(worker_ids = NULL, controller = NULL)
worker_ids |
Optional vector of worker ids. If |

The controller to use. If not given (or |
A character vector, NA
where nothing is being worked on,
otherwise corresponding to a task id.
obj <- rrq_controller("rrq:example")
rrq_worker_list(controller = obj)
# This example might be a bit racy: we need to run a task that
# sleeps, and then sleep a little bit for the task to be picked up
# by a worker. Typically this happens very quickly but there are
# no guarantees.
t <- rrq_task_create_expr(Sys.sleep(1), controller = obj)
Sys.sleep(.2)
rrq_worker_task_id(controller = obj)
# You can always find out which worker did work on a task though:
rrq_task_info(t, controller = obj)$worker
