Hi guys, wow, thank you so much for your quick replies even if it's sunday!!
It really looks like that one way to go is to move the responsibility of _id generation for the booking to whatever other storage engine like redis so that we maybe end-up with something like a _id microservice here. However, we need to investigate which approach fits our use case best. Thanks for the 4.0 preview, it sounds really promising, looking forward to it!! Olaf
