Orchestrates multiple Disco.Aggregate together.

This module is a GenServer implementation that can handle more than one aggregate in the same place. A common problem, for example, arises when working with umbrella projects, where a module can be used to run all the commands and queries without exposing internal list of available aggregates.

Usage example

The usage is similar to Disco.Aggregate, except that this is a GenServer, so it needs to be started before using it. In a real scenario, maybe you’ll want to put in under some supervisor.

NOTE: Disco.Factories.ExampleAggregate has been defined in test/support/examples/example_aggregate.ex.

iex> {:ok, pid} = Disco.Orchestrator.start_link [Disco.Factories.ExampleAggregate]
iex> is_pid(pid)
true
iex> Disco.Orchestrator.commands()
[:do_something]
iex> Disco.Orchestrator.routes()
[:find_something]
iex> Disco.Orchestrator.dispatch(:do_something, %{foo: "bar"})
{:ok, %Disco.Factories.ExampleAggregate{foo: "bar", id: "4fd98a9e-8d6f-4e35-a8fc-aca5544596cb"}}
iex> Disco.Orchestrator.query(:find_something, %{foo: "bar"})
%{foo: "bar"}
