How to make hibernate commit fast and efficient?
I have 1000 threads and there task is to increase the value by 1 update to the database . So for eg :
Initally my database has the value 0, first thread come it increases the value to 1 , then 2nd thread come it increases that value to 2 , then 3rd come it increases the value to 3 and so on till 1000 threads , so at the end when 1000th thread come it changes the value to 1000 from 999.
I have written the code and the code is working perfectly but the problem is it is taking more than a minute to update those values ,so how to minimize that time so that 1000 threads can update it in least time .
public String increaseAndUpdateNumber() {
Session session = getSession();
try {
synchronized (this) {
int number = dao.getNumberdao().getNumberCount(session);
Number numberObj = dao.getNumberdao().getByNumber(session,number);
//begin of transaction
Transaction numberTx = session.beginTransaction();
number+=1;
System.out.println("number is :"+number+" numberObj :"+numberObj);
numberObj.setNumber(number);
dao.getNumberdao().update(session, numberObj);
numberTx.commit();
//end of transaction
}
return "success";
}catch(Exception e){
e.printStackTrace();
}finally {
session.close();
}
return null;
}
Act these 1000 threads in the least time possible.

The problem is that the database updates must happen one after the other to reflect serial increment of the number. This will be a choking point for the 1000 threads. If speed is so important, then you may have to create a custom data layer that replicates the relevant database tables in memory as objects and only persists changes back to the database periodically.
