SYNOPSIS

$rp = MongoDB::WriteConcern->new(); # w:1, wtimeout: 1000

    w        => 'majority',
    wtimeout => 10000, # milliseconds

DESCRIPTION

A write concern describes the guarantee that MongoDB provides when reporting on the success of a write operation.

For core documentation on read preference see http://docs.mongodb.org/manual/core/read-preference/.

ATTRIBUTES

w

Specifies the desired acknowledgement level. Defaults to '1'.

wtimeout

Specifies how long to wait for the write concern to be satisfied (in milliseonds). Defaults to 1000.

j

The j option confirms that the mongod instance has written the data to the on-disk journal. Defaults to false.

Note: specifying a write concern that set j to a true value may result in an error with a mongod or mongos running with --nojournal option now errors.
