I have been avoiding Amazon DynamoDB for a long time. Each time I tried to use it, either with PHP or GoLang always gave up very quickly. A while ago, I built up a solution storing a lot of JSON files on S3 buckets, and the costs of this solution (number of GET requests) started to escalate very quickly. I decided to try to migrate data to DynamoDB, and this time I was successful. I will try to explain how I did it and what I learned along the way.

Documentation for mod_rewrite is pretty good, but it is not always easy to test your rules. This is a simple way to test your rules. I found this tool very useful when I was working on a project that required a lot of htaccess rules.

Postman, it’s a great tool for debuging, testing and other activities performed by us - developers. It has a build in option to sign requestes with AWS Signature . We do have AWS SDK for Go v2 , but I couldn’t find any good examples except a test file . The other useful file will be const.go where we can find a couple of interesting variables.

I wanted to implement a timeout in go routines. There are a couple o ways doing that. We could use context.WithTimeout() or we go with classical sync.WaitGroup group with a trick.

Let’s start with the first one.

This one is really quick and easy to set up public bucket policy on DigitalOcean Spaces . Spaces are S3 type object storage, you can check out about it here .
