Concurrent Data Processing in Elixir: JobSupervisor does not go down (page 54)
After finishing Chapter 2, Long-Running Processes Using GenServer, I was able to successfully run the code. but if I see the process observer, I can see the JobSupervisor processes still alive. Is this the expected behavior? If I have created 100,000 jobs, there will be 100,000 active supervisors.
This is how my supervision tree looks like when triggered 3 jobs. 2 jobs are finished.
