Elixir Nodes

Elixir Nodes task implementation

Prerequisities

Erlang OTP 21+ and Elixir 1.8.1+

Configure it:

The application is configurable, the possible configurations are:

  • default_timeout - Timeout in ms, default value is 500.
  • max_timeout_multiplier - Timeout multiplier, default value is 4.
  • table_name - The name of ETS table, default name is :state.

Usage:

  • Nodes.new_node 1 - takes integers as IDs. Tries to create a new node. Returns {:ok, {node_id, node_pid}} or {:error,reason}.
  • Nodes.get_state 1 - takes given ID and if the given node exists, returns the state of the node, or {:error, reason}.
  • Nodes.get_all_states - takes no arguments. Returns states of all nodes in a list. If there are no nodes, returns an empty list.
  • Nodes.kill_node 1 - tries to terminate the node by given ID. Returns either true if the node was killed, or false if not (possibly because it was killed by someone else or just did not exist).
