DESCRIPTION
A Read Concern describes the constraints that MongoDB must satisfy when reading data. Read Concern was introduced in MongoDB 3.2.ATTRIBUTES
level
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 <http://docs.mongodb.org/manual/search/?query=readConcern> in the MongoDB documentation for more details.
This may be set in a connection string with the the "readConcernLevel" option.
