How KafScale solves backpressure, retries, and coordination without a central orchestrator
Part 3 closes the series with the stuff that actually breaks multi-agent systems in production: backpressure, retries, duplicate work, and brittle “orchestrator brains” that become a single point of failure. KafScale flips the model by leaning on Kafka’s native primitives instead of layering custom coordination logic on top. Consumer groups give you horizontal scaling without manual load balancing. Partition lag becomes real, observable backpressure instead of hidden queues that explode memory. Retries and dead-letter topics turn failures into routable events, not cascading outages. And because the log is durable, you get replay and “time travel” debugging for free, which means you can validate new agents and models against historical traffic without touching live flows.
