NAME

       mongoc_read_concern_t - Read Concern abstraction

SYNOPSIS

       NOTE
              New in MongoDB 3.2 and mongoc 1.3.0

       The  mongoc_read_concern_t  allows  clients  to choose a level of isolation for their reads. The default,
       MONGOC_READ_CONCERN_LEVEL_LOCAL, is right for the great majority of applications.

       You can specify a read concern on connection objects, database objects, or collection objects.

       See readConcern on the MongoDB website for more information.

       Read Concern is only sent to MongoDB when it has explicitly been set by mongoc_read_concern_set_level  to
       anything other then empty string.

READ CONCERN LEVELS

       MONGOC_READ_CONCERN_LEVEL_LOCAL ("local")
              Default. The query will return the node’s most recent copy of data. Provides no guarantee that the
              data has been written to a majority of the nodes.

       MONGOC_READ_CONCERN_LEVEL_MAJORITY ("majority")
              The  query will return the node’s most recent copy of the data confirmed as having been written to
              a majority of the nodes.
