Registry in Elixir 1.4

Manage process identifiers easily with Registry

Clearly I could register the GenServer through the Registry, which … Might mean I can find the GenServer by asking the Registry… ?

And yeah, you can look these registry entries up manually to locate the PID.

I have some functions I wrote in my GitHub example that show how I can hit the registry to…

Every process in an OTP app has some sort of identifier. By default it will use a PID like `#PID<0.80.0>`.

If I make a single GenServer that just gets started and does something on its own, this is no big deal and the PID is fine. But we may want to name a GenServer so we’re not using the PID all the time. We can do…

Good questions. I’ll do my best to answer them.

What’s the benefit of starting the Registry process as a supervisor vs a worker ?

To be honest, I just followed the documentation for Registry and have stuck with this supervisor syntax they show (see this section).
