I'm also wondering if there's any update on this;

I have successfully been able to implement an external EventBus/Store via an extension on the EventBus, but am not able to the same for the CommandBus? I could share my EventBus extension, if it's needed (as an example) or if anyone is interested?

I have an example repo which illustrates how this can be achieved using Kafka (see here https://github.com/bradsheppard/nest-cqrs-kafka-example). It would be good to have this in the docs though. I don't mind putting up a PR to add it.

Also an example repo of external eventbus in use with REDIS here! Hope this help somebody :)

@kamilmysliwiec Do you expect to provide some example in a near future ? Sounds like a production grade feature. Neither intel with https://github.com/nestjs/docs.nestjs.com/issues/957
