A 3-day bug hunt on a 3-person team costs up to €7,200 in lost engineering time. This workshop teaches you to prevent that — unit tests, data tests, and integration tests for PySpark and Databricks Lakeflow, including Spark Declarative Pipelines.
My backlog of data engineering design patterns candidates starts to fill in and when it happens, it's *the* moment to make some space for new ideas. That's why today you won't read about Apache Spark or Databricks but about a data engineer design pattern.
