Migrating C++ driver

Complete the following procedure to migrate your existing DataStax C++ driver to a version that is capable of connecting to Astra databases created using DataStax Astra DB.

In your existing DataStax C++ driver code, modify the connection code to use the Astra DB API.

Both the DataStax C driver for Apache Cassandra and the {company} Enterprise (DSE) C driver use the same code to connect and query your Astra database. When using the DSE C++ driver, use the header #include <dse.h>.

The secure_connect_bundle must include the absolute path to your Astra database credentials (secure-connect-database_name.zip).

cass_cluster_set_credentials(cluster, "clientId", "clientSecret");

  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 *
  }

Build and link your application against the DataStax C++ driver for Apache Cassandra.
- Linux or macOS
  
  For static linking, use cassandra_static.a or dse_static.a.
  cc connect_database.c -I/path/to/cassandra.h -L/path/to/cassandra.so -lcassandra
- Windows Include these libraries in your Microsoft Visual Studio project by adding them to the project’s properties under ]Configuration Properties/Linker/Input/Additional Dependencies.
  
  For static linking, use cassandra_static.lib pass:c[.
Link your application against cassandra.lib. Your application will also require `cassandra.dll to be in your runtime path.
