MongomapperFallback

At this time, MongoMapper not have any mechanism to properly handle Replicaset connection failures (commonly master falls down and arbiter was not selected any server yet).

MongomapperFallback is a alternative to handle these failures with a simple retry mechanism.

Installation

Add this line to your application's Gemfile:

gem 'mongomapper_fallback'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mongomapper_fallback

Usage

# example.rb
class Example
  include MongomapperFallback

  def execute
    logger = Logger.new('your_logfile_here.log') # or Slogger

    # available options:
    # - retry_limit: limit of retries that will be executed
    # - sig_quit: sends a QUIT to current process before retry failed code again

    replicaset_safe_run!(logger, retry_limit: 10, sig_quit: true) do
      # perform any operation
    end
  end
end
