alt Hacker NewsIts a bit messy to do parallelism with it but it still works and its a consistent pattern and their are libraries that add it for the processing of slices and such. It could be made easier IMO, they are trying to dissuade its use but its actually really common to want to process N things distributed across multiple CPUs nowadays.
True. But in my experience, the pattern of just using short lived goroutines via errgroup or a channel based semaphore, will typically get you full utilization across all cores assuming your limit is high enough.
Perhaps less guaranteed in patterns that feed a fixed limited number of long running goroutines.
