Connecting to DataStax Astra Database-as-a-Service using a secure connection bundle

Use the following code snippet to connect your database:

   #include <cassandra.h>
   #include <stdio.h>

   int main(int argc, char* argv[]) {
     /* Setup and connect to cluster */
     CassCluster* cluster = cass_cluster_new();
     CassSession* session = cass_session_new();

     /* Setup driver to connect to the cloud using the secure connection bundle */
     const char* secure_connect_bundle = "/path/to/";
     if (cass_cluster_set_cloud_secure_connection_bundle(cluster, secure_connect_bundle) != CASS_OK) {
       fprintf(stderr, "Unable to configure cloud using the secure connection bundle: %s\n",
       return 1;

     /* Set credentials provided when creating your database */
     cass_cluster_set_credentials(cluster, "username", "password");

     CassFuture* connect_future = cass_session_connect(session, cluster);

     if (cass_future_error_code(connect_future) == CASS_OK) {
       /* Use the session to run queries */
     } else {
       /* Handle error */


     return 0;

Note: cass_cluster_set_contact_points() and cass_cluster_set_ssl() should not used in conjunction with cass_cluster_set_cloud_secure_connection_bundle().
