rrq_task_info: Fetch task information

In mrc-ide/rrq: Simple Redis Queue

Fetch task information

Description

Fetch information about a task. This currently includes information about where a task is (or was) running and information about any retry chain, but will expand in future. The format of the output here is subject to change (and will probably get a nice print method) but the values present in the output will be included in any future update.

Usage

rrq_task_info(task_id, controller = NULL)

Arguments

task_id	A single task identifier
controller	The controller to use. If not given (or NULL) we'll use the controller registered with rrq_default_controller_set().

Value

A list, format currently subject to change

Examples

obj <- rrq_controller("rrq:example")

# Get information about a task
t <- rrq_task_create_expr(runif(1), controller = obj)
rrq_task_info(t, controller = obj)

# If the task has been retried, the retry chain is shown
rrq_task_wait(t, controller = obj)
rrq_task_retry(t, controller = obj)
rrq_task_info(t, controller = obj)

# If the task was queued onto a separate process, then this
# information is shown
rrq_task_create_expr(1 + 1, separate_process = TRUE, timeout_task_run = 60,
                      controller = obj)
rrq_task_wait(t, controller = obj)
rrq_task_info(t, controller = obj)
