Go Sync or Go Home: WaitGroup



Go’s goroutines, channels, and mutexes make it easy to develop complex concurrency systems. Most problems can be solved using these three mechanisms, but you might be asking yourself — what else is out there?



That’s what I was wondering when I stumbled upon the lesser-known features of the sync and x/sync packages. In this blog series, I will explore some of these niche features, focusing on practical use cases and how they can be used to boost performance and reduce latency.
