Hibernateのカスケード複数オブジェクトを削除する最速の方法

Question

2つのカスケード・レベルを持つオブジェクトを削除するのにHibernateを使用しています。オブジェクトを照会して削除して見たいときに問題が非常に遅いですより速い方法があれば。 15個のStatementオブジェクトを削除するのに約15〜30秒かかります私のコードは、次のようになります。

session.createQuery("delete from Statement where batchId = ?").setParameter(0, batchId).executeUpdate(); 

が、問題は、削除カスケードにはないということです。

public void deleteStatement(Long batchId) { 
    List<Statement> statements = session.createQuery("from Statement where batchId = ?").setParameter(0, batchId).list(); 
    for(Statement statement : statements) { 
     session.delete(statement); 
     logger.debug("Deleted statement"); 
    } 
} 

私はちょうど行うことができます知っていますこの方法で発生します。オブジェクトを削除してカスケードが発生する効率的な方法はありますか、あるいは間違っていることがありますか？

ありがとうございました！

davidfrancisに対応して、ここで生成冬眠SQLの言い換えです。それは狂っていて、何千もの行があり、それを信じるかどうかは分かりません!!注意してください。私のドメインオブジェクトStatementには、トランザクションのセットを含むInvoiceのセットが含まれています。私はすべての私のコレクションを読み込むのが怠惰です、btw。今

最も速い方法は、手動で削除を行うことです。カスケードに頼るのではなく、それぞれの子に対して別々のdeleteステートメントを使用する必要があります。一時的に外部キーの関係に違反しないように、子を最初に削除する必要があります。

また、プロキシフェッチを使用して速度を上げることもできます。ほとんどの場合、必要のないデータを取得するために費やされる可能性があります。プロキシのフェッチを使用するとき、HibernateはIDをフェッチし、プロキシオブジェクトを作成します。プロキシオブジェクトは、初めて使用されるときにインスタンス化します。ただし、すぐに削除するので、インスタンス化する必要はありません。
