[erlang-questions] Stopping a master process and all its workers
Thu Apr 12 14:45:48 CEST 2018
I am a bit in doubt about what would be the cleanest way to stop a part of
my supervision tree.
The tree looks like this:
I have multiple instances of the top_sup supervisor, one for each master.
So when I need to stop a master and all its workers I would have to stop
its top_sup and everything below it.
Controlled stopping needs to be different from a crash as a controlled stop
should remove some persistent data for the master and workers.
Should I just do an exit(top_sup, normal) for the controlled stop?
Or should I implement a stop function all the way down?
Are there any subtleties that I need to cater for? Have I given enough
information for this question to make sense?
Either will do the job. Just wondering what experience others have on this.
