Interactive Consumer Groups Example (Routing Events)
This example shows how Customer Groups work, i.e. how to decide which handlers receive which events.
Consumer Group is a concept used in Apache Kafka®, but many other Pub/Subs use a similar mechanism.
The example uses Watermill and Redis Streams Pub/Sub, but the same idea applies to other Pub/Subs as well.
Live video
This example was showcased on the Watermill v1.2 Launch Event. You can see the recording on YouTube (starts at 17:00).
Running
docker-compose up
Then visit localhost:8080 and check the examples in each tab.
Screenshots
Code
See crm-service and newsletter-service for the Watermill handlers setup.
How does it work?
This example uses SSE for pushing events to the frontend UI. See the other example on SEE for more details.
