Is there a pattern which will allow us to send a single message to a channel which will then persist.The source can replace the message simply by sending another one, this means the latest message is the only important one. The channel can have many subscribers and any late subscribers should pick up the latest message.
The use case is a kind of dynamic configuration where clients can pick up the interesting config data from a message in a channel. I'm not sure if this is a misuse of Camel though, or whether it's simple not applicable for all Camel components. It;s worth noting that the clients only need the message once to work. If they channel is not available they simply don't get updates.
