Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by thekashyap …, we narrowed down the problem to calls to Entity Beans taking long time.

While creating 50000 instances of a… particular entity in DB, performance is terrible because of 50000 … Re: Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by ~s.o.s~ If all you would want to do is import/insert some bulk data in your database, you are better off using a specialized/optimized approach rather than the plain old inserts wrapped under some stupid managed bean method invocations. Given that you are OK with solutions like using a CSV file, I'd assume that using Java is not a requirement here. In that… Re: Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by thekashyap Use of Java is mandatory, but given the amount of data to be loaded, we can switch to something else (like a call from Java code to do csv load) during the flow. I would check up what you suggested. Looks interesting. One other question if you know: Does hibernate help in improving "insert" performance? Or is it only for read/update? … Re: Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by ~s.o.s~ > Does hibernate help in improving "insert" performance? Or is it only for > read/update? Any persistence framework you use would only impact your performance when it comes to bulk inserts; be it iBatis or Hibernate. But still, if you are stuck with using Hibernate, I'd recommend checking out the Hibernate mailing list for more … Re: Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by thekashyap >> Any persistence framework you use would only impact your performance when it comes to bulk inserts; I suppose the impact is positive. Could you confirm? Abt the commits, AFAIK currently given the way code is written, it's not an option to switch it off. But we would look into it. Again the link you provided is quite interesting, we'll … Re: Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by ~s.o.s~ > I suppose the impact is positive. Could you confirm? Not sure what you mean by positive here; given that yet another layer of abstraction is being used, it would only end up hurting the performance. When it comes to plain and simple inserts without any business logic, nothing can beat the bulk load capabilities offered by your database. I … Re: Mass update: What to use instead of (J2EE) Entity Beans 14 Years Ago by jwenting To use Java: 1) create a stored procedure in the database that schedules a bulk update batch and takes the data to be used as a parameter 2) use Java to call that stored procedure. That's how we do it here to drive bulk inserts through upload of data files from a web application, works a charm.
