Is there some sort of trick (apart from saving a project and running a windows task to initiate it) within FME to set a clock as a tranformer to count to 1hour before starting the next transformer? I basically want a count time timer workbench transformer to wait 1 hour before starting the next one.
There is a user custom transformer on FME hub called WorkspacePauser that does exactly what you need. Just set the timer to 3600 seconds. It works with FME 2017 and above.
There is a Decelerator Transformer, but I'm unsure of the maximum amount of time you can pause a function--it is measured out in seconds.
If you are using the .bat code created in fme, you could modify it to add a pause between workflows. Again, measured in seconds.
Pausing for an hour between transformers seems excessive--how many transformers do you have to iterate through?
I like the Decelerator Transformer option that @MaryBeth suggested. It's probably the most straight-forward.
Another option, would be the Python Caller Transformer and incorporate the sleep function in the time module. Something like this:
import time time.sleep(3600)
You can read about the time module here.
If you only want to make sure, that the current workspace has finished writing, I would suggest to use the Shutdown Python Script. You additionally can access several FME variables (for example if the workbench finished successfully or not).
