我使用opentracing-cassandra-driver-3来跟踪来自spring启动应用程序的apache cassandra db调用。虽然我在jaegerui上看到了db跟踪，但是跟踪没有Map到父跨度。有办法实现吗？

QuerySpanNameProvider querySpanNameProvider = FullQuerySpanName.newBuilder().build();
    Cluster.Builder builder = Cluster.builder().addContactPoints("127.0.0.1").withPort(9042);
    Cluster cluster = new TracingCluster(builder, tracer, querySpanNameProvider);
    Session tracingSession = cluster.newSession();
