Hibernate에서 여러 객체를 연속적으로 삭제하는 가장 빠른 방법

Question

최대 절전 모드를 사용하여 두 개의 계단식 수준이있는 객체를 삭제할 때 객체를 쿼리 한 다음 삭제할 때 매우 느립니다. 보는 데 관심이 있습니다. 더 빠른 방법이 있다면. 나는 다만 수 알고

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"); 
    } 
} 

: 15 Statement 개체를 삭제하는 15-30 초 정도 걸립니다 내 코드는 다음과 같습니다

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

그러나 문제는 삭제 폭포가 없다는 것입니다 이 방법으로 발생합니다. 효율적인 방법으로 내 개체를 삭제하고 여전히 계단식 현상이 발생 했습니까? 아니면 제가 잘못하고있는 것이 있습니까?

도움 주셔서 감사합니다.

davidfrancis에 대한 응답으로, 여기에 생성 최대 절전 모드 SQL의 의역이다. 그것은 미치고 길이 수천 라인, 믿거 나 말거나 !! 참고로, 내 도메인 객체 인 Statement에는 Transaction 세트가 들어있는 Invoice 세트가 들어있다. 나는 내 컬렉션을 모두로드하는 것을 게으 르네, btw. 이제

Answer 1

가장 빠른 방법은 삭제를 수동으로 수행하는 것입니다. 캐스케이드에 의존하기보다는 각 자식에 대해 별도의 delete 문을 사용해야합니다. 일시적으로 외래 키 관계를 위반하지 않도록 먼저 하위 키를 삭제해야합니다.

또는 프록시 가져 오기를 사용하여 속도를 높일 수 있습니다. 대부분의 시간은 필요하지 않은 데이터를 가져 오는 데 소비됩니다. 프록시 페칭을 사용할 때 Hibernate는 id를 가져오고 처음 사용될 때 자신을 인스턴스화 할 프록시 객체를 만든다. 그러나 즉시 삭제하기 때문에 인스턴스화 할 필요가 없습니다.
