In this post I talk about the type Channels and Select available under the sync package. While Channels can be used for both communication between concurrent processes, they can also be used in synchronisation by sharing the memory address. Select allows you to pseudo-randomly resolve one of the available/ready case.

Continuing the sync package series, in this post I talk about the type sync.Once and sync.Pool available under the sync package. While sync.Once offers a once.Do(func() {}) signature that is perfect for initialising most of the clients in your application. While sync.Pool{New: func() interface{}}, lets you do things like warming up, managing and creation of pool of resources.

Memory access synchronisation is one of the popular ways to achieve concurrency in various languages. Sync package is one of the major difference between these languages and Go. The package provides you new set of concurrency primitives with wide abilities on top of the memory access synchronisation primitives. I am going to briefly talk about some commonly used tools from this package.
