I'm getting started with an OpenDXL service to convey a "fire-and-forget" message, which message needs to be acted upon by just one of N redundant clients.
What's a good approach for this? Events will go to all N clients, who aren't aware of each others' existence and don't have a concept of an elected leader or active master. Should I have a request/response message, but set the timeout to immediate and ignore timeouts?
