NAME

       mongoc_read_prefs_set_hedge - mongoc_read_prefs_set_hedge()

SYNOPSIS

          void
          mongoc_read_prefs_set_hedge (mongoc_read_prefs_t *read_prefs,
                                       const bson_t *hedge);

PARAMETERS

       • read_prefs: A mongoc_read_prefs_t.

       • hedge: A bson_t.

DESCRIPTION

       Sets  the  hedge  document  to  be  used for the read preference. Sharded clusters running
       MongoDB 4.4 or later can dispatch read operations in parallel, returning the  result  from
       the fastest host and cancelling the unfinished operations.

       For example, this is a valid hedge document

          {
             enabled: true
          }

       Appropriate values for the enabled key are true or false.
