FsBunny

FsBunny implements a streaming API over RabbitMQ optimized for implementation of event-driven systems.

The core idea is that while there are many streams carrying many messages using many serializers, each stream is dedicated to a single type of message serialized using certain serializer.

It works under the assumptions that:

• We never want to lose a message
• The exchange + topic tells us the message type (as well as serialization format)
• The consumer is long-lived and handles only one type of message
• The consumer decides when to pull the next message of a queue
• The publishers can be long- or short-lived and address any topic
• We have multiple serialization formats and may want to add new ones easily

These assumptions may not be suitable in all scenarios, but they map extremely well to event-driven processing.
