Abstraction Suggestions

Summary: use good/established messaging patterns like Enterprise Integration Patterns. Don't make up your own. Don't expose transport implementation details to your application.

Broker

As much as possible, I prefer to hide Rabbit's implementation details from my application. In .Net we have a Broker abstraction that can communicate through a lot of different transports (rabbit just happens to be our preferred one). The broker allows us to expose a very simple API which is basically:

  • publish
  • request
  • start/stop subscription

arobson / Topic Matching
Created May 24, 2012
Fun with applied FP
View Topic Matching
Subscribers subscribe to topics.
A topic is expressed as a period delimited namespace: "a.b.c.d"
A topic subscription may be an exact match or use wild card characters:
* - match 1 namespace segment at a specific location
# - match any number of namespace segments
When a message comes in, it will always have a fully specified topic.
The list of subscriptions with topics that would match the message's topic is the desired outcome.
