Compilation failures when creating keyspace

[hackmad]

I've been following the README to get the project up and running. When I add the example Schema.Keyspace module, I get compile time errors. I have a very basic Elixir application running against a single node Cassandra in docker.

The error message we get:

$ iex -S mix
Erlang/OTP 21 [erts-10.3.5] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe] [dtrace]

Compiling 3 files (.ex)

== Compilation error in file lib/schema_user.ex ==
** (exit) exited in: GenServer.call(DBConnection.Watcher, {:watch, DBConnection.ConnectionPool.PoolSupervisor, [#PID<0.173.0>, #Reference<0.1861776828.1076232197.26507>, Xandra.Connection, [prepared_cache: #Reference<0.1861776828.1076232197.26500>, pool: DBConnection.ConnectionPool, idle_interval: 30000, default_consistency: :one, address: '127.0.0.1', port: 9042]]}, :infinity)
    ** (EXIT) no process: the process is not alive or there's no process currently associated with the given name, possibly because its application isn't started

Is there something I'm missing? Also, is there a way to disable the compile time schema creation?

Please see the code below.

mix.exs:

defmodule Cassie.MixProject do
  use Mix.Project

  def project do
    [
      app: :cassie,
      version: "0.1.0",
      elixir: "~> 1.8",
      start_permanent: Mix.env() == :prod,
      deps: deps()
    ]
  end

  # Run "mix help compile.app" to learn about applications.
  def application do
    [
      extra_applications: [:logger],
      mod: {Cassie.Application, []}
    ]
  end

  # Run "mix help deps" to learn about dependencies.
  defp deps do
    [{:triton, "~> 0.2"}]
  end
end

config.exs:

use Mix.Config

config :triton,
  clusters: [
    [
      conn: Triton.Conn,
      nodes: ["127.0.0.1"],
      pool: Xandra.Cluster,
      underlying_pool: DBConnection.Poolboy,
      pool_size: 10,
      keyspace: "my_keyspace",
      health_check_delay: 2500,  # optional: (default is 5000)
      health_check_interval: 500  # optional: (default is 1000)
    ]
  ]

application.ex:

defmodule Cassie.Application do
  @moduledoc false

  use Application

  def start(_type, _args) do
    children = []

    opts = [strategy: :one_for_one, name: Cassie.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

schema_keyspace.ex:

defmodule Schema.Keyspace do
  use Triton.Keyspace

  keyspace :my_keyspace, conn: Triton.Conn do
    with_options [
      replication: "{'class' : 'SimpleStrategy', 'replication_factor': 1}"
    ]
  end
end

defmodule Cassie do
  def hello do
    :world
  end

You can either force Xandra to 0.10.0 or use this: https://github.com/theblitzapp/triton.git. There's an outstanding PR here: #22

I'm using 0.2.4 and am still encountering this issue. This problem exists while using Xandra 0.12 and 0.13 though using 0.10 seems to work with some CQL errors.

Edit: I see that using the current master branch works. The CQL errors were my fault. Could it therefore be of interest to get a new release out?
