Automated Airflow or orchestrator DAGs running daily scheduled queries with execution date parameters.
target_date = "2026-08-30"
min_amount = 500
query = f"SELECT * FROM v_sales_transactions WHERE transaction_date = '{target_date}' AND amount >= {min_amount}"
df_filtered = spark.sql(query)Practice typing production-grade PySpark code for Dynamic Parameter Injection in Spark SQL.
