We do a *lot* of testing, including long-running tests and large
database size tests. We're trying to add more and more tests,
robustness and compatibility are key goals for many of us on this team.
If you really need a production-level support, you should probably go
through Sun (Java DB) or IBM (Cloudscape).

Hi,
We need to include a database along with our Java-based desktop
application, and for deployment/maintenance reasons, an embedded
database would be ideal. I’m evaluating whether derby will suit our
needs, and so far I really like what I see. However, some colleagues
have told me that they had evaluated derby in the past (a few months
ago), and that they passed on it after seeing memory leak problems which
resulted in OutOfMemoryException. The application may need to run for a
long time, and may generate a very large amount of data, therefore, a
recurring memory leak is a showstopper. I wanted to give Derby another
look before moving on.
I looked through JIRA to try to identify bugs related to memory leaks.
I found:
DERBY-756 (fixed; reported against 10.1.2.1, but doesn’t say which
version the fix is applied to)
DERBY-912
I skipped over these because they appear to be client/server (please
correct me if I’m wrong):
DERBY-210
DERBY-557
I also browsed the derby-user list, but didn’t find anything
substantive. So, on to my questions:
How stable, robust, and well-tested is derby? How often do critical
bugs find their way into production releases (please include “memory
leaks” in the definition of critical)? How long does it take for bugs
such as the above to make their way into a production release, and when
could I reasonably expect these two to be available for production? Are
there other outstanding memory/leak related bugs which I’m not aware
of? Would you recommend Derby for my project?
Thanks,
Jim Newsham
