#485: Topic-based pub/sub for IResourceChangeListener --------------------------+--------------- Reporter: olemis | Owner: Type: enhancement | Status: new Priority: major | Version: Resolution: | --------------------------+--------------- Resource listeners often will watch events for a limited , well-known set of resource realms (e.g. `ticket` + `attachment` ) .
The current dispatching strategy (i.e. `match_resource`) is mostly [http://en.wikipedia.org/wiki/Publish–subscribe_pattern#Message_filtering content based] . It behaves in `O(r * l)` order of magnitude . This might lead to a lot of extra (unnecessary) overhead . A performance improvement could be to allow listeners to register to dedicated realm channels (i.e. [http://en.wikipedia.org/wiki/Publish–subscribe_pattern#Message_filtering topic-based filtering]) , thus turning the dispatch algorithm into `O(l)` . PS: We shall not loose the current content-based filtering capabilities , so in advance I advocated using a hybrid strategy . -- Ticket URL: <https://issues.apache.org/bloodhound/ticket/485> Apache Bloodhound <https://issues.apache.org/bloodhound/> The Apache Bloodhound (incubating) issue tracker
