nodejsNode.js CPU‑Bound Offload: worker_threads, cluster, child_process & chunking
When Node.js services hit CPU‑bound work, the event loop stalls. This guide maps four off‑load strategies—worker_threads, cluster, child_process, and cooperative chunking—to constraints like shared memory, fault isolation, deployment topology, and latency SLOs, and shows a worker‑pool example.
Node.js Worker Threads: Offloading CPU‑Bound Work Without Blocking the Event Loop
Node's event loop can freeze during CPU-intensive work. Worker Threads (stable since v12) let you offload that work to parallel threads, keeping the main loop responsive.
