Hi Flavio, "With this solution, depending on how fast the subscriber reacts, the message could be garbage collected by the time the subscriber comes in and says "oldest sequence id", no? In my understanding, the property you're looking for can only be guaranteed in a best-effort fashion, the system can't guarantee it will be there." ------- You are right, so I suggest to slightly change current message garbage collection strategy in previous mail: "For idea 1), we also need to change current message garbage collection behavior in Hedwig: for topic with no subscriber, keep the message with messageBound limit instead of deleting all messages."
Thanks, Jiannan
