Subject EI Pattern question
Date Wed, 26 Mar 2008 20:22:55 GMT


i have often the following scenario and would like to solve it with an EIP,
but don't know, if a pattern 
exists :

I have 

- one or more/many (stateful) event producers, may be reporting external
contact state changes

- many consumers, which connect/disconnect/reconnect many times over time

All (many) producers are sending message for each contact state change to
one or more destinations.

The clients does not know any of the producers, but on start/restart they
need to get all last contact states and after the initial sync they should
receive state change messages.

Any idea for a simple solution this with Camel and an EIP ?
