ManifoldCF would benefit from a generic push agent
--------------------------------------------------
Key: CONNECTORS-233
URL: https://issues.apache.org/jira/browse/CONNECTORS-233
Project: ManifoldCF
Issue Type: New Feature
Components: Framework agents process
Affects Versions: ManifoldCF next
Reporter: Karl Wright
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.
