You are right, and I do prefer KahaDB due to its performance (as long as LevelDB seems to be just "beta-stable"). Such a decision needs to be made after careful consideration of the trade-offs. On the strength of our past experience some customers have much less traffic resp. no the highest performance requirements, so a journaledJdbc Adapter could help for some time.
A permanently "self-healing" KahaDB would be a huge advantage to simplify long-term operation in my point of view.
