Ted Ross commented on DISPATCH-367:
-----------------------------------
For the record...
This Jira is requesting an enhancement that is arguably meaningless but will
improve the way balanced distribution looks to casual testers. The fix for
this is also simple and inexpensive, so it's probably worthwhile.
The problem is that if a tester tests balanced distribution with a single
synchronous sender, the distribution doesn't look very balanced, even though it
is behaving reasonably. With a single synchronous sender, there are never any
previous deliveries in-flight, so the delivery always goes to the "first" local
consumer.
Balanced delivery tries to deliver messages to the consumer with the fewest
outstanding (unsettled) deliveries. The value of balanced distribution doesn't
really kick in until there are multiple in-flight deliveries to the same
address with multiple consumers.
> balanced distribution needs to be more... balanced.
