Horde

Horde packages a distributed Supervisor and Registry built on δ-CRDTs.

Installation

If available in Hex, the package can be installed by adding horde to your list of dependencies in mix.exs:

def deps do
  [
    {:horde, "~> 0.1.0"}
  ]
end

Usage

Public APIs of Supervisor and Registry have been reproduced as faithfully as possible. Horde.Supervisor and Horde.Registry should function more or less as drop-in replacements.

{:ok, supervisor} = Horde.Supervisor.start_link([], node_id: :distributed_supervisor_1, strategy: :one_for_one)

Horde.Supervisor.start_child(supervisor, child_spec)

Horde runs inside Erlang clustering (but might later be ported to use other transport methods). Joining up supervisors or registries must be done manually:

Horde.Tracker.join_hordes(supervisor_1, supervisor_2)

Leaving a horde is also possible:

Horde.Tracker.leave_hordes(supervisor_2)
