Hi all,

I have heard of scalability issues with a few applications where Hibernate is used. Please let me know in case anyone has faced any such issues. Also, please let me know of the possible cause for this.

Thanks,

Hat's off to the Hibernate team for created a great product.

As for the scalability issues that you have heard about well... In my experience these issues are caused by developers who leverage Hibernate's features without any regard to optimizing them. Hibernate will do exactly what it is told to. If 4 tables are queried as a Cartesian product Hibernate will return all the data in object form which can be very expensive. Also, a lot of the here say about Hibernate's inability to scale, or its performance issues come from DBAs who have seen these queries run rampant, or are unwilling/reluctant to relinquish control over the data.

All in all Hibernate makes developing Java applications more maintainable if developers take the time to learn it.

well said dcshock!

Hi. I was interested in understanding some bigger reference sites using Hibernate in order to validate the maximum number of connections / concurrent users it will support ie. is there a limit and can it be used for an industrial strength solution. What are the biggest sites that use this?

Hi,

Thanks for the great important information.
