  Appfuel::Configuration.define :aws do
    defaults region: 'us-west-2'

      optional(:secret_access_key).filled(:str?)
      optional(:kms_master_key_id).filled(:str?)
      optional(:kms_data_key_cipher).filled(:str?)
    }
  end
end

.db_definition ⇒ Object

Defines database configuration. This is designed to hold more than one database connection which is why they are named invidually. We are using active record so the config is taylored to that style connection.

Configuration Overview

pool: Managed connection which controls the amount of thread access to

a limited number of database connections

adapter: We always use postgres, rarely changes encoding: We always use unicode, rarely changes database Name of the database username Name of the database user password Database password host Location of the database server

pid_path           Sneakers   daemon's pidfile location
workers            Sneakers   the number of worker processes
threads            Sneakers   number of threads per worker
prefetch           RabbitMQ   how many messages to send to a worker
timeout_job_after  Sneakers   Maximal seconds to wait for job
start_worker_delay Sneakers   Delay between thread startup
durable            RabbitMQ   Queue should persist
exchange           RabbitMQ   name of the exchange
exchange_type      RabbitMQ   type of exchange (direct, topic, fanout)
vhost              RabbitMQ   name of the vhost

.worker_definition ⇒ Object

Defines the configuration for the whole worker. It basically has two child definitions :db and :sneakers

Configuration Overview

env: The environement this worker is deployed as dev, qa, stg, prod logfile: The location of the application log file if the value is

stdout or stderr it will use that instead

dispatchers List of workers that dispatch messages to actions. The reason

why you would want more than one is to use different exchange
types

db Database configuration please see sp_offers/config/database sneakers RabbitMQ configuration please see sp_offers/config/sneakers aws Configuration S3 where we store our documents
