Summary 0002829: BAM persistent topics
Description (rep by Chris Chen)

 don't have a fully concrete idea either but there are two sides to
this subscription feature - client and server. The server side may be
similar to how JMS EJB beans or Jabber Server side components work.
The EJB side has a defined set of beans listening to a particular
topic/queue. This is considered a subscription. As for persistent
subscriptions, it can be similar to how JMS works as well. A client
registers as a subscriber for a particular topic. Unless the client
unsubscribes, the system will continue to store messages for this
subscriber when the subscriber is offline. Of course, this comes with
its own set of challenges. Fiorano MQ and ESB has a setting to
periodically flush out any persistent messages.

XMPP by nature has persistence message supported in some sense (ie. I
get chat messages that were sent when I wasn't logged on). I wonder
if a Jini-like persistence capability may be something to model after
or even relevant in this case. Either way, persistent and
subscription do go hand in hand.
