      MongoDatabase database = client.getDatabase("myDatabase");
      MongoCollection<Document> collection = database.getCollection("myCollection");
       
      // Start client session, which is causally consistent by default
      try (ClientSession session = client.startSession(ClientSessionOptions.builder().build())) {
        //Run causally related operations within the session
        collection.insertOne(session, ...);
        collection.updateOne(session, ...);
       
        try (MongoCursor<Document> cursor = collection.find(session).filter(...).iterator()) {
          while (cursor.hasNext()) {
            Document cur = cursor.next();
          }
