Observability - Metrics • Based on Kubernetes/Prometheus/Grafana • Builtin framework and Go runtime collectors，Export APIs for user to add their own metrics • Declare Prometheus annotations for service discovery

to get right, but • Goroutines and channels made it manageable. "In the same way that garbage collectors improve upon malloc and free, we found that goroutines and channels improve upon the lock-based

we should also consider the fact that too many pointers will increase the pressure of garbage collectors at run time. So whether large-size struct and array types or their corresponding pointer types until fmt.Println is called, then we can use a runtime.KeepAlive function call to tell garbage collectors that the slice bs and the value parts referenced by it are still in use. For example, package
