How to make discard notifications reliable?
we have a producer and a consumer which are using direct messaging. The producer starts sending an infinite stream of messages after the consumer subscribes.
Can the consumer reliably detect that some messages in the middle of the message stream were discarded?
Is it enough to
(1) send all messages with the same priority
(2) and turn off message eliding
(3) and avoid using topic dispatch
to ensure that discard indications are reliable?
