# 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](https://www.youtube.com/live/wjnd0Hj6CaM?t=1020) (starts at 17:00).

## How does it work?
|
|
|
|
This example uses SSE for pushing events to the frontend UI. See the [other example on SEE](../server-sent-events) for more details.
