Concurrency in Go (Golang)

Questions that comes to all Developers is whether they are utilising the available Computing resource efficiently? 

Course Overview

The course could be divided into five parts.

• Concurrency Primitives

• Deep Dive into Concurrency Primitives

• Concurrency Patterns

• Context Package

• Bonus Section - Interfaces

In the course we try to answer these questions.

Concurrency Primitives

• What are the limitations of Threads?

• What are advantages of goroutines over OS threads?

• How do we avoid race condition?

• How Channels are used to communicate data?

• How do we implement timeout and non-blocking communication?

• When do we use mutex and channels?

• How to synchronise execution of goroutines?

• How to detect race condition in Go?

Deep Dives into Concurrency Primitives

• How Go scheduler works?

• How does context switching works?

• How channel send and receive works underneath?

Concurrency Patterns

• How to construct streaming pipelines with Goroutines and Channels?

• How to Fan-out and Fan-in computationally intensive stages?

• How do we avoid Goroutine Leaks?

Context Package

• How we can propagate request scoped data and cancellation signal across API boundaries?

Coding Exercises

• Each concept is followed by a Coding Exercise.

• Exercises blueprint are shared on Github.

Sample Applications

We will build

• Blueprint of web crawler.

• Image processing pipeline.

• HTTP Server Timeouts with Context Package.

Bonus Section - Interfaces

• How to define common behaviour between different objects as abstract type?

• How Interface provides an abstraction for higher level functions?
