C/C++ DataStax Enterprise Driver

This driver is built on top of the C/C++ driver for Apache Cassandra, with specific extensions for DataStax Enterprise (DSE).

This software can be used solely with DataStax Enterprise. See the License section below.

Features

Documentation

Documentation for the DSE driver is found here.

Examples

The driver includes several examples in the examples directory for using DSE specific features.

A Simple Example

Connecting the driver is is the same as the core C/C++ driver except that dse.h should be included instead of cassandra.h which is automatically included by dse.h.

/* Include the DSE driver */
#include <dse.h>

int main() {
  /* Setup and connect to cluster */
  CassFuture* connect_future = NULL;
  CassCluster* cluster = cass_cluster_new();
  CassSession* session = cass_session_new();

  /* Add contact points */
  cass_cluster_set_contact_points(cluster, "127.0.0.1");

  /* Provide the cluster object as configuration to connect the session */
  connect_future = cass_session_connect(session, cluster);

  if (cass_future_error_code(connect_future) == CASS_OK) {

    /* Run queries here */

    /* Close the session */
    close_future = cass_session_close(session);
    cass_future_wait(close_future);
    cass_future_free(close_future);
  } else {
    /* Handle error */
    const char* message;
    size_t message_length;
    cass_future_error_message(connect_future, &message, &message_length);
    fprintf(stderr, "Unable to connect: '%.*s'\n", (int)message_length,
                                                        message);
  }

  /* Cleanup driver objects */
  cass_future_free(connect_future);
  cass_cluster_free(cluster);
  cass_session_free(session);

  return 0;
}
