errgroup
A drop-in alternative to Go's sync/errgroup with configurable goroutine worker limits for rate-limited operations.
What is errgroup?
neilotoole/errgroup is a Go package that extends the standard library's sync/errgroup with configurable goroutine limits. It solves the problem of unbounded goroutine creation when working with rate-limited APIs, databases, or other constrained resources by providing worker pool semantics while maintaining the same API interface.
Go developers building concurrent applications that interact with rate-limited external services, databases with connection limits, or any system where controlling goroutine concurrency is necessary.
Developers choose this package because it provides a drop-in replacement for sync/errgroup with added concurrency control, allowing them to limit goroutine creation without changing their existing error group patterns, and it can offer performance benefits for specific workloads when properly tuned.
