merlimat commented on issue #2954: Broker considers fail-over consumer priority-level URL: https://github.com/apache/pulsar/pull/2954#issuecomment-437114596 The question is that broker is using ordinal position for consumers to ensure even distribution. Simple example: 4 partitions, 2 consumers. With equal priorities, they partition | consumer -------| ---- t-partition-0 | c-1 t-partition-1 | c-2 t-partition-2 | c-1 t-partition-3 | c-2 If I set c-1 with higher priority, I would expect to have c1 on all the partitions. however the priority will only affect the sorting, so each partition will see the same list of consumers `[c1, c2]`, ordered by priority, but will keep doing the same assigment as above, given that on partition-3 with chose the consumer index with `N % len(consumers)`
