Browsing around, I really struggle to find a suitable answer to this question.
I've tried my chance with Mongo's Two-phase commits as decribed here : http://docs.mongodb.org/manual/tutorial/perform-two-phase-commits/ but it seems to be tedious and lacks distributed transactions with other tiers.
I would also need strong arguments regarding toughness and reliability.
Does anyone have achieved a successfull study or implementation in production on this ?
My underlying need is to add a Document Oriented persistence to a JCR implementation.
Thank's for helping
