Cassnadra大型集合插入了C#中的嵌套对象

在与Cassandra数据库进行了长期斗争后，我写下了这个问题。我想插入电影对象的大集合（约1000000）：

    public class Movie
    {
        public Guid Id { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public int Year { get; set; }
        public string Genres { get; set; }
        public int Rating { get; set; }
        public string OriginalLanguage { get; set; }
        public string ProductionCountry { get; set; }
        public int VotingsNumber { get; set; }
        public Director Director { get; set; }
    }

带嵌套字段控制器：

    public class Director
    {
        public Guid Id { get; set; }
        public string Firstname { get; set; }
        public string Lastname { get; set; }
        public int Age { get; set; }
    }

我正在使用DataStax C#驱动程序，并以不同的方式绑定，但仍然没有。目前我的代码如下：

    private void CreateSchema()
    {
        Session.Execute("CREATE KEYSPACE IF NOT EXISTS test WITH replication " +
                        "= {'class':'SimpleStrategy', 'replication_factor':3};");
        Session.Execute("CREATE TYPE IF NOT EXISTS test.director (" +
                        "firstname text," +
                        "lastname text," +
                        "age int," +
                        ");");
        Session.Execute("CREATE TABLE IF NOT EXISTS test.Movies (" +
                        "id uuid," +
                        "title text," +
                        "description text," +
                        "year int," +
                        "genres text," +
                        "rating int," +
                        "originallanguage text," +
                        "productioncountry text," +
                        "votingsnumber int," +
                        "director frozen<director>," +
                        "PRIMARY KEY (id)" +
                        ");");
    }
    public string TimeOfCollectionInsert(int collectionEntriesNumber)
    {
        var watch = new Stopwatch();
        try
        {
            IList<Movie> moviesList = Movie.CreateMoviesCollectionForCassandra(collectionEntriesNumber);
            var preparedStatements = new List<PreparedStatement>();
            var statementBinding = new List<BoundStatement>();
            for (int i = 0; i < collectionEntriesNumber; i++)
            {
                preparedStatements.Add(Session.Prepare("INSERT INTO test.Movies (id, title, description, year, genres, rating, originallanguage, productioncountry, votingsnumber, actors) VALUES (?,?,?,?,?,?,?,?,?,{ 'director': { firstname: 'DirectorName', lastname: 'DirectorLastname', age: 50 }});"));
            }
            for (int i = 0; i < collectionEntriesNumber; i++)
            {
                statementBinding.Add(preparedStatements[i].Bind(moviesList[i].Id, moviesList[i].Title, moviesList[i].Description, moviesList[i].Year, moviesList[i].Genres, moviesList[i].Rating, moviesList[i].OriginalLanguage, moviesList[i].ProductionCountry, moviesList[i].VotingsNumber));
            }
            watch.Start();
            for (int i = 0; i < collectionEntriesNumber; i++)
            {
                Session.Execute(statementBinding[i]);
            }
            watch.Stop();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
        return watch.ElapsedMilliseconds.ToString();
    }

这两种方法都运行成功，但我希望动态创建控制器。如果有任何帮助，我将不胜感激

顺便说一句 这是衡量卡桑德拉批量插入性能的好方法吗？

谢谢，P
