Implmenting Timeout in Golang

Problems

• If the response time is too long, the users may have left this page, but the server is still consuming resources to process, and the result obtained is meaningless.
• Too long server-side processing will cost too much resources, resulting in a decline in concurrency, and even service unavailability

Why Go timeout control is necessary?

Go is normally used to write backend services. Generally, a request is completed by multiple serial or parallel subtasks. Each subtask may issue another internal request. When the request times out, it’s better to return quickly and release the occupied resources, such as goroutines, file descriptors, etc.

Common timeout control on the server side

• In-process processing
• Serving client requests, such as HTTP or RPC requests
• Calling other services, including calling RPC or accessing DB, etc.

Golang vs. Node.JS: Who Trumps the Battle of Backend Frameworks?

Full blog here

The backend of your application is truly the essential part of your product. No matter how much you appreciate the design, the application’s success lies in its backend. A scalable backend that effectively implements the required business logic is the primary goal of programmers.

Therefore, it is crucial to choose the most powerful and scalable technology. There are plenty of languages ​​in the market that can form the backend of any application, Node.js and Golang are the two most popular technologies among them.

They are real and developed languages ​​that have recently been used in various outstanding projects. Golang is an open-source programming language, whereas Node.js is an open-source server framework. They both are gaining popularity for various reasons.

According to a development stat, it is observed that almost 50% out of 58,543 respondents use Node.js as their preferred app development tool.

Golang, on the other hand, has overtaken other programming languages in the application development market and has gained huge recognition over the past few years.

But, which backend framework is best for you? In this article, I’ll make a healthy comparison of two of Google’s most popular backend development tools based on several essential features and various other factors.

“Go Has Indeed Become The Language Of Cloud Infrastructure“ - Rob Pike

Introduction

We spoke to Rob Pike, the co-author of the Go programming language, about a career spanning four decades, the evolution of Go over the last ten years, and into the future.

The Interview

Evrone: Unlike many developers today, you started your career decades ago at Bell Labs. What’s been the biggest change in the way we develop software that you can think of, given your rare perspective?

**Rob: **The scale is much bigger today. Not just of the computers and the network, but the programs themselves. All of Unix version 6 (circa 1975) fits comfortably on a single RK05 disk pack, which has just over 2MB of storage, with lots of room left over for user software. And that was a fine computing environment, or at least seemed like one at the time. Although I can, of course, explain much of the growth, it is astonishing and perhaps not all of it is justified.

Gopher-reading-list: A Curated Selection Of Blog Posts on Go

Gopher Reading List

中文版

Here is a reading list of blog posts about Go. It aspires to include only the most useful and relevant material that anyone writing Go should eventually read. By definition, the list is a work in progress.

Rather than being comprehensive, the list is a curated selection fixed at 200 entries.

Go is growing fast and so are the number of blog posts about it. If an interested reader knows of a great post not on this list, please open an issue with a link to the post. Not every blog post linked in an issue will make its way into the list. Nonetheless, the issue list (both open and closed) is a good source of additional reading material.

NOTE: Any new additions will need to replace something else on the list to keep it at a fixed length.
