Hello,
is it possible to run from fme system call (or python caller) and don't wait for the result?
Solved
SystemCaller without waiting for result
Best answer by david_r
The SystemCaller is synchronous, but you can use a PythonCaller with something like the following to execute an external command asynchronously:
import subprocess
my_command = subprocess.Popen(['command1.exe', 'args1', 'arg2'],
stdin=None, stdout=None, stderr=None, close_fds=True)This will execute "command1.exe" with the arguments "args1" and "args2" and FME will continue the workspace without waiting for the result.

Hi @witos
Would you like to send the results by email, for example?
Thanks,

Hi @danilo_fme. It is not needed. In my ptyhon script that will be executed I will have some code to update database once it is finished, but if it is possible to send email or do web api call then why not. I just want to know what are the possibilities.
It is very easy to use this transform. You can do download here:

Perfect. You can to integration with API. There is a interesting custom transform TwilioCaller and TwilioSMSSender.

No, there isn't such an option not to wait for the result from a program executed via SystemCaller or PythonCaller.
If necessary, consider creating another workspace containing the WorkspaceRunner (Wait for Job Complete: No) to run the workspace which contains the SystemCaller or the PythonCaller.

😍 Just what I needed right now...
And when I finish the external command with triggering a webhook to a workspace with the second half of the process, it saves me 10 hours of running-but-actually-idle engine capacity.

😕 It works, as long as the workspace (and the python-environment in which I did pOpen) is alive. As soon as the workspace stops, the python-environent stops and so does the external process I triggered...
So no silently running process outside of FME, which wil trigger the next step when done.
