MongoDB::WriteConcern - Encapsulate and validate a write concern
version v2.2.2
$rp = MongoDB::WriteConcern->new(); # w:1, wtimeout: 1000
$rp = MongoDB::WriteConcern->new(
w => 'majority',
wtimeout => 10000, # milliseconds
);
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/.
Specifies the desired acknowledgement level. If not set, the
server default will be used, which is usually ``1''.
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).
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.
