OK, I will add to that issue , but for the record here is our machine type and the env vars: This GCP hardware has 64 virtual CPUs (a hyperthread on a 2.6GHz Xeon E5), with 416GB memory. This is shared among other docker containers, of course, but as the trace file shows, our process uses 8

Thanks for your answer :), even though the original question has been deleted. I've used the reflect.NewAt to allocate a new memory at the same address of the unexported field's reflect.Value, it seems work. for unexported not nil field if !v.CanSet() { v = reflect.NewAt(v.Type(),

Hi, I would like to understand a bit better one particular implementation decision regarding the new sync.Map feature. Besides having to introduce a new keyword to the language and some compiler work, what were the other issues that pushed the implementation as part of the standard library

Go makes it easy to use intermediates, and the code will be easier to read for someone else, possibly years from now. { intervalMS := *Int64Flag_xxIntervalMS interval := time.Duration(intervalMS) * time.Millisecond elapsed := time.Now().Sub(timeStart) time.Sleep( interval -

I think we have a similar setup to what you are trying to do, we also started with Scala and about 3 years ago we moved it to Go (still use Scala for other parts of our app). While working in Scala and other languages you are encourage to abstract things as much as you can, in Go it is often
