Could you build this?
No Building enterprise-grade distributed RPC infrastructure atop Apache Kafka requires deep distributed systems engineering, fault tolerance, and high-throughput network programming that AI vibe coding cannot reliably architect.
What it would actually take: Such a system typically uses Go or Java/Scala integrated with low-level Kafka APIs, gRPC, and custom wire protocols. The core difficulty lies in managing partition rebalances, exactly-once or at-least-once message delivery semantics, sub-millisecond request/reply correlation at scale, backpressure, and network partitioning edge cases. Successfully executing this requires deep domain expertise in distributed systems and systems architecture.
