19       A Read Concern describes the constraints that MongoDB must satisfy when
20       reading data.  Read Concern was introduced in MongoDB 3.2.
21

ATTRIBUTES

23   level
24       The read concern level determines the consistency level required of
25       data being read.
26
27       The default level is "undef", which means the server will use its
28       configured default.
29
30       If the level is set to "local", reads will return the latest data a
31       server has locally.
32
33       Additional levels are storage engine specific.  See Read Concern
34       <http://docs.mongodb.org/manual/search/?query=readConcern> in the
35       MongoDB documentation for more details.
36
37       This may be set in a connection string with the the "readConcernLevel"
38       option.
