Implementation Blueprint: Production PySpark Pipeline Framework
A production-ready PySpark codebase template featuring modular DataFrame transformations, structured JSON logging, PyTest unit testing harnesses with Chispa, Delta Lake write patterns, and GitHub Actions CI/CD workflows.
Key Highlight: Pure DataFrame transformations should never instantiate SparkSession directly; pass DataFrames explicitly to enable fast unit testing.
