Hi Sage: I see there are two difference between luminous and upstream after the patch of *fast dispatch peering events* 1. When handle pg query w/o pg, luminous will preject history since the epoch_send in query and create pg if within the same interval. but upstream now will reply empty info or log directly w/o create the pg. My question is : can we do this on luminous? 2. When handle pg notify w/o pg, luminous will preject history since the epoch_send of notify and give up next creating if not within the same interval. but upstream now will create the pg unconditionally, If it was stray, auth primary will purge it later. Here my question is: is the behavior of upstream a specially designed improvement? I would appreciate it if you could give some explication, thanks!
