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.
The power of Big Data processing platforms resides mainly in the ability to parallelize processing on different nodes. Each framework has its own unit of parallelism. In Spark it's called partition. Apache Beam calls it bundle.
