> ManifoldCF has a pull agent which crawls to get what it needs. There is, however, no "push" agents available. Developing a JSON-based push agent would demonstrate how to write one of these entities, and if done properly would also be useful in many off-the-shelf situations where notification is used.
> The most common model would involve an API to which change notifications could be reliably posted. A database table would maintain a list of the documents that needed processing, like the jobqueue. Fetching of documents would then need to be performed through a pluggable interface similar in some respects to IRepositoryConnector, but which would differ because version strings are unneeded. Indexing, of course, would proceed through the agents framework.
> I would anticipate that such an exercise would lead to some changes in the way the agents framework is structured. It is also possible to imagine that instead of a push agent, a notification service could be added to the pull-agent which would effectively do the same thing. Choosing the right approach would be part of this ticket.
