Hi,

My team is currently using Hibernate 2.1.8 and I honestly love this product. The question I have is are there any real performance related benefits to upgrade to 3.0.5+ version ?

We are using Oracle 9 as an back-end database.

Would appreciate any comments,
Paul

subselect fetching
multiple outer-join collection fetching in a single query

Thank you, Gavin, for a quick response.

Do you have any comparison benchmarks that I can use to promote the
migration ?

No, I mean a drop in replacement is not going to be quicker. You need to write your app to specifically take advantage of these new features.

But, trust me, HB3 is a much better product. The only kind of apps that shouldn't upgrade are those in pure maintenence mode.

Use your own, vendor benchmarks are alwas fake.

I would like to clarify some of the enhancements you described.

What specific areas should I pay attention to in my application ?
Is it related to mapping changes I need to make to take a leverage of the enhancements ?

Or is it a quantity of SELECTs that is produced as a result of the query or criteria request that contains multiple eager relationship fetches ?

Thanks in advance for clarifications,
Paul
