🐔 What happened with my project on the Rinha de Backend challenge

I participated in the Rinha de backend (pt-BR) or “Backend Rooster Fight” in English challenge and I was super excited to see the results of my super hacky and performant solution.

The results were scheduled to be published at 21:00 BRT (2 AM CEST my local time). So I stayed up til later that night grabbed popcorn, and waited for the results.

Well, I wish I hadn’t waited…

📂 Go: Importig a CSV to PostgreSQL

contents of a CSV file with each column in a different color

If you are using Go ad PostgreSQL, and need to performa a bulk import a CSV, it’s most likely you will find the COPY protocol is the feature that suits you better. In that direction, you will find examples using pgx CopyFrom that relies on the native protocol, and it’s fairly easy to use. However, depending how it’s used you can have an exponencial increase of memory consumption of your application making it unreliable and more expensive to run.
