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.
Two great features whose I experienced when I have been working with Dataflow were the serverless character and the auto-scalability. That's why when I first saw the Apache Spark on Kubernetes initiative, I was more than happy to write one day the pipelines automatically adapting to the workload. That also encouraged me to discover the horizontal scalability and this post is the first result of my recent research on that topic.
