Extension:EventBus

The EventBus extension propagates state changes (edit, move, delete, revision visibility, etc) to an EventGate instance, providing consumers of the service with the means of tracking changes to MediaWiki content.

Known issues
Ideally, this sort of change propagation would be atomic, that is to say, if one of the tracked changes is committed in MediaWiki, the corresponding event is guaranteed to be delivered (even if by eventual consistency). As this extension is hook-based, that is not currently the case; Truly reliable event delivery will likely require something bound to the corresponding database transaction. (tracked in .)

Configuration
Note: For this extension to be useful, you need to have Kafka installed with EventGate as the event-intake service.

To enable the sending of state events, add the following to your, with the event service name and URLs set according to your environment.

Purge events
MediaWiki core provides CDN purges to its EventRelayer, which is null by default. To enable sending CDN purges to EventGate/Kafka as well, use the EventBus adapter for EventRelayer as follows.
