## What it is
A Node.js library that distributes processing tasks across multiple child processes with a simple API. It provides call durability, automatically re-queuing tasks if a child process dies, plus configurable concurrency options.

## Use cases
- run CPU-heavy tasks in parallel across child processes
- offload work from the main Node event loop
- isolate crash-prone native code like JVM calls from the main process
- retry tasks automatically when a worker process dies
- limit concurrent worker processes with custom concurrency settings

## When to choose
- you need durable, retry-safe task execution in Node.js child processes
- you want a minimal API without a heavy job-queue framework
- you must isolate unstable native or JVM workloads from your main process

## When to avoid
- you need a distributed job queue across machines
- your workload is I/O-bound and async handles it fine
- you want modern worker_threads instead of child processes

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency, workflow-automation
- domain: developer-tools, backend, microservices
- platform: cross-platform
- tags: worker-processes, child-process, task-distribution, cpu-bound, nodejs
