[jira] [Updated] (QPID-5466) Dispatch - Add different forwarding
semantics for addresses
[ https://issues.apache.org/jira/browse/QPID-5466?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ted Ross updated QPID-5466:
---------------------------
Description:
(For version 0.2)
At present, if there are multiple receivers for a particular address, Dispatch delivers a copy of each message to all of the receivers. This feature adds the ability to by-configuration deliver messages to only one of those receivers.
The configuration for this feature is per-address and defines two settings:
- _fanout_ is either Multiple or Single (and a placeholder for Group). Multiple fanout means all subscribers receive each message. Single fanout means that only one subscriber receives the message.
- _bias_ controls how single-fanout is treated. The following values for bias are provided:
-- _Closest_ - each message is delivered to the closest/least-cost subscriber.
-- _Spread_ - messages are spread indeterminately across all subscribers.
-- _Latency_ - (not implemented yet) Messages are delivered in a balanced way to all subscribers based on the latency of acknowledgements. This mode attempts to keep all subscribers equally fed with incoming messages.
