🤔 THE QUESTION

How do we construct a complete, self-contained PySpark script from session creation to action execution?

💡 WHAT IS IT?

A standard PySpark workflow initializing a session, constructing a distributed dataset, and triggering an action.

🎯 WHAT IS IT USED FOR?

The foundational blueprint for all standalone PySpark jobs, scheduled cron tasks, and batch ETL scripts.

💻 EXAMPLE

from pyspark.sql import SparkSession

spark = SparkSession.builder \
    .appName("IngestOrders") \
    .getOrCreate()

orders_df = spark.createDataFrame(
    [(101, "Delivered", 250.0), (102, "Pending", 80.0)],
    ["order_id", "status", "amount"]
)
orders_df.show()
