- Processing records sequentially can be slow; concurrency speeds it up.
- Waitgroups in Go's sync package simplify goroutine management.
- Each goroutine increments the waitgroup counter; decrements when done.
- Mismanagement of waitgroups can lead to deadlocks or panics.
- Go 1.25 introduces wg.Go for automatic goroutine management.
- New version eliminates manual counter management issues.
- Go 1.25 also improves CPU detection in Kubernetes environments.
- Future posts will explore more sync package functionalities.
