Could you build this?
No Writing a high-performance thread-per-core message queue in Zig using Linux io_uring requires mastery of systems programming, lock-free concurrency, and kernel async primitives.
What it would actually take: Requires low-level Zig systems programming utilizing raw Linux syscalls via io_uring for zero-copy TCP socket read/write operations and event rings. The architecture demands a strict thread-per-core execution model (similar to Seastar), CPU core pinning, ring buffer IPC, and precise implementation of the NATS protocol spec under high memory and concurrency constraints.
Discussion
20 comments analyzed.
Competitors mentioned: NATS, Claude Code, MQTT
Concerns raised: Project abandoned/unmaintained by author, Website and GitHub repo taken down, Single commit history suggests low effort or AI-generated code, No message durability guarantees (YOLO delivery only), Not production-ready
Feature requests: Easy setup with fewer configuration options, Reliable clustering without Kubernetes, Improved message semantics to prevent Heisenbugs, Better focus on usability over raw performance
