ContinuousTask [expr]
represents a task in which expr is continuously reevaluated.
ContinuousTask [expr,end]
represents a task in which expr is continuously reevaluated until the time specified by end.
ContinuousTask [expr,tspan]
represents a task in which expr is continuously reevaluated over the time span tspan.

ContinuousTask [expr]
represents a task in which expr is continuously reevaluated.
ContinuousTask [expr,end]
represents a task in which expr is continuously reevaluated until the time specified by end.
ContinuousTask [expr,tspan]
represents a task in which expr is continuously reevaluated over the time span tspan.
Details and Options
- CloudSubmit [ContinuousTask[expr]] submits expr for continuous reevaluation in the cloud, starting immediately.
- Unless they contain blocking functions or Pause specifications, continuous tasks will typically make use of all available processor resources.
- ContinuousTask is intended primarily for private cloud installations, not the public Wolfram Cloud.
- If the evaluation of expr leads to abnormal termination or yields $Failed or a Failure object, a series of restarts will be attempted after progressively longer time intervals.
- Continuous tasks can be controlled using functions like TaskSuspend and TaskResume .
- The following options can be given:
-
- In ContinuousTask [expr,end], end can be a DateObject or any other date and time specifier.
- In ContinuousTask [expr,tspan], tspan can be any Quantity object representing a time span.
Examples
Basic Examples (2)
Deploy a continuous task, requesting notifications for all discrete runs:

Prepare a cloud object containing a counter:
Update the counter from a continuous task:
Verify the counter has been updated:
Pause the task:
The counter is no longer updating:
Delete the counter and task:
