Terry Wilson 2013-12-13 20:27:32 UTC Doc Text A bug in the QPID topic consumer re-connection logic (under the v2 topology) incorrectly resulted in the creation of duplicate RPC notifications delivered to every subscribed consumer. As a result, samples derived from RPC notifications were duplicated to the extent that the collector service made multiple subscriptions to the topic control exchanges for individual services (e.g. nova).

With this release, QPID now creates a single queue for each topic, to be shared among all consumers of that topic. This ensures that each RPC notification is only received by a single consumer, preventing any unnecessary duplication of samples.

Prior to this update, QPID topic consumer re-connection logic (under the v2 topology) incorrectly resulted in the creation of duplicate RPC notifications delivered to every subscribed consumer. Consequently, samples derived from RPC notifications were duplicated to the extent that the collector service made multiple subscriptions to the topic control exchanges for individual services (e.g. Compute).
With this release, QPID creates a single queue per topic and shares it among all corresponding consumers. This ensures that each RPC notification is only received by a single consumer, and prevents any unnecessary duplication of samples.
