Dapr(or it's subset) in the Ray ecosystem or Service Choreography


I was wondering if someone could contrast dapr(https://dapr.io/) with Ray.

  • In particular, is there a pub/sub system in the Ray ecosystem or native to Ray. I guess a sub feature is triggers.

I believe Ray Workflows is more a case of service orchestration. I’m looking more for what I think is called Service Choreography(i.e. the pub/sub model)

Hi @rabraham, Ray doesn’t provide pubsub as user-facing APIs today but I believe you might be able to build one with the actor/task APIs. The challenging part will be durability and consistency, depending on the delivery guarantee you want to achieve.
