MongoDB::ReadConcern - Encapsulate and validate a read concern
version v2.2.2
$rc = MongoDB::ReadConcern->new(); # no defaults
$rc = MongoDB::ReadConcern->new(
level => 'local',
);
A Read Concern describes the constraints that MongoDB must satisfy when reading
data. Read Concern was introduced in MongoDB 3.2.
The read concern level determines the consistency level required
of data being read.
The default level is undef, which means the server will use its configured
default.
If the level is set to ``local'', reads will return the latest data a server has
locally.
Additional levels are storage engine specific. See Read Concern in the MongoDB
documentation for more details.
This may be set in a connection string with the the readConcernLevel option.
