Regarding StreamRecord, is the UID still required? In my understanding we
are working towards state-snapshotting, so that would not require to have IDs
in records anymore, correct? I mentioned at some earlier point that the IDs are
not used anymore, so what's the status now?
If we got rid of the UID then we can also get rid of StreamRecord and
StreamRecord serializer.
