Elixir connect to cassandra example

conn.ex

defmodule Conn do
  def test do
    {ok, client} = :cqerl.new_client({})

    {ok, result} = :cqerl.run_query(client, "SELECT * FROM demodb.users;")
    rows = :cqerl.all_rows(result)
  end
end

mix.exs

defmodule SomeProject.Mixfile do
  use Mix.Project
  
  ##
  # bla, bla, bla...
  ##

  def application do
    [applications: [:cqerl]]
  end

  defp deps do
    [{:cqerl, github: "matehat/cqerl", ref: "HEAD"}]
  end
end

cool! 👍 but how would I set the configuration of cqerl? like cluster and nodes? from within my elixir server?
