I have not made any claim on how to use the code. You can call transaction.commit() after each object modification, if you like. Also, I assume that anyone interested in mongopersist is aware that MongoDB does not provide transaction safety. That said, I think that a large class of applications (or large parts of an app) does not need transaction safety. In our application, for example, most object modifications are compartmentalized, so that modifying small sets of objects is pretty safe. The largest risk is posed by competing modifications, which I tried to address using optional write-conflict detection. Regards, Stephan -- Entrepreneur and Software Geek Google me.
