NAME
    MongoDB::WriteConcern - Encapsulate and validate a write concern

VERSION
    version v2.2.2

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

        $rp = MongoDB::WriteConcern->new(
            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. If not set, the server default will be used, which
    is usually "1".

  wtimeout
    Specifies how long to wait for the write concern to be satisfied (in milliseconds). Defaults to
    1000. If you set this to undef, it could block indefinitely (or until socket timeout is
    reached).

  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.
