I get that and I’m familiar with the concept of a buffer. My confusion is about this part:
all subscribers receive the exact set of historical data, regardless of when they subscribe
If the publisher emits n items after some subscriber s subscribes but before some other subscriber t subscribes, and both s and t are meant to receive the exact set of historical data regardless of when they subscribe, don’t the n items emitted before t subscribes need to be buffered until then?
