COMPRESSING DATA TO AND FROM MONGODB

       MongoDB 3.4 added Snappy compression  support,  while  zlib  compression  was  added  in  3.6,  and  zstd
       compression  in  4.2.  To enable compression support the client must be configured with which compressors
       to use:

          mongoc_client_t *client = NULL;
          client = mongoc_client_new ("mongodb://localhost:27017/?compressors=snappy,zlib,zstd");

       The compressors option specifies the priority order of compressors the client wants to use. Messages  are
       compressed if the client and server share any compressors in common.

       Note  that  the  compressor  used by the server might not be the same compressor as the client used.  For
       example, if the client uses the connection  string  compressors=zlib,snappy  the  client  will  use  zlib
       compression  to  send data (if possible), but the server might still reply using snappy, depending on how
       the server was configured.

       The driver must be built with zlib and/or snappy and/or zstd support to enable compression  support,  any
       unknown (or not compiled in) compressor value will be ignored.
