@AmericanJeff thanks for that… I also believe the C implementation has some form of distributed element to it. The Java “port” doesn’t have anything like that… you have to roll your own support for non-integrated databases. Interesting that you note the codebases are distinct, I have thought they were related but perhaps this is just PR from Oracle… the stability of BDB and the ubiquitous-ness of Java.

BDBJE (which is what you linked to at the beginning of the article) is not the same as the BDB used in the Oracle/Google paper. That was the C version which is a considerably older implementation and uses a much different internal structure. That said, I have a lot of experience with BDBJE and it is very fast and reliable. It’s even faster if you roll your own serialization or use their DPL.

@KesheR cool, thanks… I see they are still working on their JPA layer though. I’ll check back in 6 months.

I recently used Apache Cayenne in my current project. It works basically as Hibernate. It isn’t complex, I learned its secrets in just a couple of days. Recommended.
