Hi all,
I am new to OJB and very interested in using this tool in a new
project that
I am working on. I was just wondering how I can get information about
OJB's
performance and whether or not it is ready for production use?
OJB is used in production application since version 0.5. We have about
6.000 download each month and a wide user base using it in a large
variety of production scenarios.
We provide a regression test suite for QA. You can use this testsuite to
check if OJB works smoothly in your target environment.
(see )
http://jakarta.apache.org/ojb/platforms.html
We also provide a performance testsuite that compares OJB performance
against native JDBC. This test will give you an impression of the
performance impact OJB will have in your target environment.
(see )
http://jakarta.apache.org/ojb/performance.html
Are there
any aspects of OJB that still need improvements that I need to watch out
for?
I regard the core functionality for quite stable. If you follow the mail
archive you will see that severe bugs are very rare. Bugs are often
fixed within few hours. I don't know much commercial vendors with such
short response times...
But:
- We don't have cool graphical mapping tools yet. Our forward- and
reverse-engineering tools are not yet perfect. This is certainly an area
where we have to improve.
(Most developers are happy with editing a simple xml based mapping
repository)
- Currently we don't have our own JDO implementation. We are providing a
simple Plugin to the JDO reference implementation. By using Sun's JDO
Reference implementation and our plugin you have a full JDO compliant
O/R mapping tool. But it's no ideal solution, at least from a
performance point of view.
A full JDO implementation is in Scope for OJB 2.0.
Can I replace those parts with something else? These answers will
really help me make a decision quickly since time is an issue. As you
have
realized I am new to OJB and your patience and help is appreciated.
I hope my answer was fast enough :-)
cheers,
Thomas
