In: lib/mongoid/collections/retry.rb

Provides behaviour for retrying commands on connection failure.

Methods

Public Instance methods

Retries command on connection failures.

This is useful when using replica sets. When a primary server wents down and a command is issued, the driver will raise a Mongo::ConnectionFailure. We wait a little bit, because nodes are electing themselves, and then retry the given command.

By setting Mongoid.max_retries_on_connection_failure to a value of 0, no attempt will be made, immediately raising connection failure. Otherwise it will attempt to make the specified number of retries and then raising the exception to clients.

@example Retry the command.

  retry_on_connection_failure do
    collection.send(name, *args)
  end
