Is bring your own Jetstream as InterStepBuffer possible

[lclx868]

Is it possible to configure numaflow to use my already running Jestream as InterStepBuffer?

I don't think it is possible today easily, but it is a good feature to have. Are you planning to use some centralized JetStream?

@lclx868 - it could be supported. But could you share you use case, including how you are running standalone Jetstream cluster first?

[lclx868]

I already have a nats cluster running (5 nodes, kubernetes, jestream enabled). This Cluster is running in the same kubernetes cluster as numaflow and is already used as input and output for our numaflow workflows. So yeah it's kind of using a centralized jetstream.

I will convert this to an issue #3131
