Distributed Computing with Go

By: V.N. Nikhil Anurag

Overview of this book

Distributed Computing with Go gives developers with a good idea how basic Go development works the tools to fulfill the true potential of Golang development in a world of concurrent web and cloud applications. Nikhil starts out by setting up a professional Go development environment. Then you’ll learn the basic concepts and practices of Golang concurrent and parallel development. You’ll find out in the new few chapters how to balance resources and data with REST and standard web approaches while keeping concurrency in mind. Most Go applications these days will run in a data center or on the cloud, which is a condition upon which the next chapter depends. There, you’ll expand your skills considerably by writing a distributed document indexing system during the next two chapters. This system has to balance a large corpus of documents with considerable analytical demands. Another use case is the way in which a web application written in Go can be consciously redesigned to take distributed features into account. The chapter is rather interesting for Go developers who have to migrate existing Go applications to computationally and memory-intensive environments. The final chapter relates to the rather onerous task of testing parallel and distributed applications, something that is not usually taught in standard computer science curricula.

The source code for Concierge has a lot of moving parts. Directly jumping into the code without any prior understanding might not be the best way to proceed. Instead, we shall take the tasks defined in the previous sections and present them as flow diagrams. However, first, let's have a brief look at the symbols and naming conventions we are using in the diagrams and code.

Code conventions

Following are the entities in Concierge:

  • payload (p): This represents the payload received to add a new document to index.
  • document (d): This represents all the metadata representing a unique document.
  • line (l): This represents all the metadata for a single line within a document.
  • token (t): This represents all the metadata...
