Daniel Platon commented on OAK-1145:
------------------------------------
I want to provide "data-feed" in XML format to a third party. That third party
periodically requests for feeds, and those feeds need to be incremental. The
feed is potentially huge (~ 1mil items) so providing incremental updates makes
sense. I plan to base these incremental updates on the EventJournal, which is
(well, used to be, in Jackrabbit 2) perfect for this, especially when I can
skip to a certain timestamp and get all {{Event.NODE_CREATED}} from there on.
Bundling up changes and making them available periodically could make sense. I
see EventJournal as an audit trail (am I wrong? is there a different feature
that covers this?) so it makes sense that the events are not immediately
available for consumption. Also, a "purge" functionality would be great. From
my experience with large system the audit trail is always a potential
performance bottleneck, so it's good to have the possibility to purge / archive
it.
Thank you.
