This is a joke. You don’t “level up beyond ETL” by speeding up SQL queries. In fact, there’s pretty much nothing about ETL in that article.

Thought this too. I liked article, had some interesting points. But never found the ETL part. Kept wondering when I'd scroll and hit the ETL section.

Maybe somebody trying out GPT for generating blog content? :mewonders:

Thanks! There's ETL in the traditional sense of moving production data to the data warehouse (hence the 'reverse ETL' moving data back into prod), as well as the term increasingly being used for data pipelines in general.

On the former, we had custom tooling at the time of writing but now use GCP Dataflow (which I can say I'm rather partial to).
