Dynamic updating

Found the thread I was looking for. This is more about having the workflow handling the scheduling vs having the scheduler:

Extract time each minute

Hi! I want to build a workflow that updates itself automatically each day at 11:00 am. I have been reading through the posts referencing batch and task scheduler but I need a simpler way. For that, my first idea is to extract the Date&Time each minute. I was thinking about the Date&Time Input and Wait nodes, maybe combined with a loop. This should give a 1x1 table with the current time. Then, whenever the result is “11:00 am”, every node in the workflow should reset and execute itself. Is t…

As per my comments there:
I see a few drawbacks such as:

1. Your workflow would constantly be running, and looping infinitely. I am not sure how efficient this is, not to mention that it would be using resources constantly.
2. What happens if the workflow is somehow stopped? What would re-trigger the workflow?
3. It would mean to have Knime open all the time. What if you need to restart Knime? What would re-trigger the workflow?
4. Based on what you explained, you are expecting the workflow to be reset by the workflow itself. I don’t think that this is possible.

With the task scheduler:

1. Your workflow does not have to keep running, therefore will only use resources whenever it runs.
2. You do not have to worry about manually triggering or re-triggering the workflow.
3. You can restart your Knime independently, and not to worry about manually triggering or re-triggering the workflow.
4. Each trigger via the command line is a new execution and has the option to reset the workflow before executing.
