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.
