Używam Hibernuj, aby usunąć obiekt, który ma dwa poziomy kaskad i moim problemem jest to, że jest BARDZO powolny, gdy pytam o obiekty, a następnie usuwam i jestem zainteresowany widzeniem jeśli jest szybszy sposób. Mój kod, który trwa około 15-30 sekund, aby usunąć 15 Statement obiektów wygląda tak:Najszybszy sposób kasowania kaskady wielu obiektów w trybie hibernacji
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");
}
}
wiem, może po prostu zrobić:
session.createQuery("delete from Statement where batchId = ?").setParameter(0, batchId).executeUpdate();
ale problemem jest to, że nie Usuwanie kaskady wystąpić z tą metodą. Czy istnieje skuteczny sposób usuwania moich obiektów i nadal występuje kaskada, czy też coś, co robię źle?
Dzięki za pomoc!

W odpowiedzi na davidfrancis, oto parafraza SQL, który generuje hibernacji. To szalone i tysiące linii, uwierz lub nie! Uwaga: mój obiekt domeny, wyciąg, zawiera zestaw faktur, który zawiera zestaw transakcji. Jestem leniwy ładując wszystkie moje kolekcje, przy okazji. Po pierwsze istnieje wiele pobierania danych, które, jak sądzę dzieje się z HQL kwerendy wybierającej:
