I read about deduplication in streams using producer name and a monotonic number. Can I use this for OCC? (Optimistic concurrency) what i want is to have a different producer names for each “aggregate”(order for example where producer name is order uuid), and each of them has a version id counter. The question is whether this scalable to use in rabbit? Having millions of producer names with separate id sequences? Do not mean that all these millions of producers can be active simultaneously.
