The Zen of Go
This article was derived from GopherCon Israel 2020 presentation. It’s also quite long. If you’d prefer a shorter version, head over to the-zen-of-go.netlify.com.
Advanced Go Concurrency
f you’ve used Go for a while you’re probably aware of some of the basic Go concurrency primitives:
- The
gokeyword for spawning goroutines - Channels, for communicating between goroutines
- The
contextpackage for propagating cancellation - The
syncandsync/atomicpackages for lower-level primitives such as mutexes and atomic memory access
These language features and packages combine to provide a very rich set of tools for building concurrent applications. What you might not have discovered yet is a set of higher-level concurrency primitives available in the “extended standard library” available at golang.org/x/sync. We’ll be taking a look at these in this article.

This tool can be even more powerful since you can enhance it with your own traces. Let’s review how it works.

The What, Why, and When of Single-Table Design with DynamoDB
Yet data modeling with DynamoDB is tricky for those used to the relational databases that have dominated for the past few decades. There are a number of quirks around data modeling with DynamoDB, but the biggest one is the recommendation from AWS to use a single table for all of your records.
In this post, we’ll do a deep dive on the concepts behind single-table design. You’ll learn:
