Learning Golang: Concurrency Pattern Publisher / Subscriber
Also known as Pub/Sub, this messaging pattern allows customers, known as subscribers, to asynchronously receive events generated by a producer, known as a publisher. Pub/Sub is a well-known pattern used in distributed systems to asynchronously communicate different services interested in learning specific information about a particular service.
In Go, we can use the concurrency primitives of the language, such as channels and goroutines, to implement this pattern.
Let me show you how.
