Hi Andrey, just to double check, if I use RIDs in my web app everything should be fine. Inserts/updates won't change any RIDs. Problems may raise if, for example, I'm storing RIDs in MySQL as reference. If then, I export and reimport the data in orientDB the RIDs may be changed and the MySQL data won't reference the right rows anymore.
Can you confirm?
