A 3-day bug hunt on a 3-person team costs up to β¬7,200 in lost engineering time. This workshop teaches you to prevent that β unit tests, data tests, and integration tests for PySpark and Databricks Lakeflow, including Spark Declarative Pipelines.
One of goals in my 3-Levels List was to get 3 certificates: AWS Cloud Practitioner, AWS Big Data and GCP Data Engineer. I've already passed the first one and that's the reason I'm writing this blog post.
