Gordon Sim commented on QPID-2104:
----------------------------------
The property used as the key should ideally be configurable also.
> Improved LVQ implementation
> ---------------------------

> Key: QPID-2104
> URL: https://issues.apache.org/jira/browse/QPID-2104
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker
> Affects Versions: 0.5
> Reporter: Gordon Sim
> Assignee: Gordon Sim
>
> My view of what ideal 'LVQ' behaviour whould be like is that the 'queue'
> would really be more like a 'topic' where the last message for each key was
> always saved. Clients would subscribe to it and receive the last message
> published for each key and subsequently any updates (i.e. any new messages).
> I.e. the consumers are always non-competing.
> Rob Godfrey also points out that if subscribers fall behind they need only be
> sent the latest for every key (i.e. any superceded values can be skipped).
