Hi folks, permission to post:
We've updated our guide on isolating Kafka consumers when testing microservice changes in a shared Kubernetes cluster (disclosure: I work at Signadot).
Even if you never touch our product, the decision space is the interesting part: message queues break the usual request-routing model for environment isolation, and the guide lays out the options (message-level routing vs topic-based isolation) and where each one fits.
