Thanks for your reply.
So how would I be able to signal to the worker that it should call exit? I
guess that is the challenge. The worker is involved in a large batch job,
and I need to be able to send a message to it to tell it to kill itself. I
had hacked out an approach using both a database table in which it would
check for the existence of a certain row, and if there remove and kill
itself, but I wondered if the framework itself provided a better way?
Also, assuming I just continue to use delete_worker in the way I am today,
is there any way possible to delete the last status the worker reported?
Thanks for your help!
