- protocol
- "tcp" or "udp"
- address
- Binding IP Address.
- port
- Port number to begin increment.
- shared_key
- A pre-shared key string to establish connections with a sender.
- log
- type
- The type of the log. "stdout", "file" or "both".
- level
- A log level. "fatal", "error", "warn", "info" or "debug".
- target
- The log file path, used when the "type" is specified as "file" or "both".
- type
- actors
- A list of actors. The format is "host_name_or_ip_address:port".
- policy
- The policy to select actors and assign a message to them. "even", "random" or "safe-random".
- timeout
- Connection timeout value for msgpack-rpc.
- get_interval
- An interval to retry the get method for msgpack-rpc.
- auth
- shared_key
- A pre-shared key string to establish connections with each receiver.
- timeout
- Authentication timeout with each receiver.
- shared_key
- show_progress
- If it is true, the sender shows you a progress bar.
- reload_receiver_plugins
- If it is true, the sender force each receiver reload plugins even in running.
- log
- type
- The type of the log. "stdout", "file" or "both".
- level
- A log level. "fatal", "error", "warn", "info" or "debug".

actory-receiver
actory-receiver -d
require 'actory'
dispacher = Actory::Sender::Dispatcher.new
res = dispatcher.message(METHOD, ARGS)You can specify an actor or actors with an argument with actors keyword.
require 'actory'
dispacher = Actory::Sender::Dispatcher.new(actors: ["localhost:18800"])
res = dispatcher.message(METHOD, ARGS)require 'actory'
actors = ["192.168.1.1:18800", "192.168.1.2:18800", "192.168.1.3:18800"]
dispacher = Actory::Sender::Dispatcher.new(actors: actors)
res = dispatcher.message(METHOD, ARGS)You can create your own plugin(s) to be executed by the receiver.
module Actory
module Receiver
class Plugin < Base
def hello(arg)
return "Hello #{arg}."
rescue => e
msg = Actory::Errors::Generator.new.json(level: "ERROR", message: e.message, backtrace: $@)
raise StandardError, msg
end
end
end
endIf you have created a plugin, put it just under the lib/actory/receiver/plugin directory. Then it will be automatically loaded even in the receiver running.
And then, you can call the method from a sender like following:
require 'actory'
dispacher = Actory::Sender::Dispatcher.new
res = dispatcher.message("hello", ["world", "actory"])The response in an array will be like following:
p res
[{"127.0.0.1:18800"=>["Hello world."]}, {"192.168.1.1:18800"=>["Hello actory."]}]Apache License, Version 2.0
