I spent the better part of the last two working days of this week trying to figure out how to write a Spark dataframe from my Azure Databricks Python notebook to an Azure blob storage container. Of course, going through that process, one thing that kept me pushing through the frustration was the thought that when I figured it out, I’d be the first to share an article on the solution with the world. That explains why this article exists. Now let’s get right into it.

BACKGROUND

My Databricks notebook does three things:

  • reads data from a CSV file in an…

I love to write elegant code. I’m going to go on a rant here but no, I’m stopping myself so we can get right into the meat of this article.

That said, let’s get straight to the business of this article.

This week at work, I had to integrate a Groovy client to Google’s nascent DLP (Data-loss prevention) API. And I’d have to admit that it’s one of the most difficult things…
