For the purely technical part In JAVA you will just need to reuse APIs you need and jgroups, you can directly reuse the component itself (plus it's dependencies ObservationManager and ComponentManager) for example. I seen there is a port of jgroups in .Net called GCT but i seems dead did not looked much at it yet. Then for any client to really receive events from an XWiki instance it mainly depends on the configuration of jgroups which has membership management. If it's important to support a large number of languages, I think JMS is better since ActiveMQ (http://activemq.apache.org/) "supports a variety of Cross Language Clients and Protocols from Java, C, C++, C#, Ruby, Perl, Python, PHP ". Note that we can write a jgroups based module now since it's the easiest for inter-XWiki/JAVA for the first target which is clustering and latter a JMS based one or any other since nobody is supposed to directly call the module so you can change it easily without touching anything else in XWiki, you can even imagine having several event distribution modules at the same time (like one basic for inter-XWiki and one readonly with larger clients languages support). > > -arvind > > > > On Mon, Jul 13, 2009 at 7:45 PM, Thomas Mortagne > <[email protected]>wrote: > >> Hi devs, >> >> I'm currently working on a network event distribution system. >> >> The goal is to be able to shared events across XWiki instance (or not >> XWiki) of a same network groups. > > > >> >> There is two target: >> - unique easy clustering channel: if every XWiki instance of a network >> group share the events it's becoming easy to make sure all instance of >> the same cluster are synchronized and not only the code which is using >> default cache system >> - a new push communication interface to know what append on a farm for >> network administrator or for softs like XWord and XEclipse to easily >> update pages list etc... >> >> To summarize I plan to do a Remote Observation Manager module which >> send events coming for Observation Manager and inject in it events >> coming for the network. >> >> See http://dev.xwiki.org/xwiki/bin/view/Design/DistributedEvents for >> more details (like events converters etc...). >> >> For now my choice is on jgroups for the network part which is simple >> to use, very configurable and well known.
