View Source K8s.Client.Mint.ConnectionRegistry (k8s v2.4.2)
A registry for open connections. As HTTP/2 allows simultaneous requests, we handle multiple requests with one process. In this case, the registry stores the PID of the HTTPAdapter which is connected according to the given connection details (URI/opts).
HTTP/1 only allows one request per connection at a time. In order to
support simultaneous requests, we need a connection pool. This is where
the :poolboy library comes in.
