Ingesting clickstream events, mobile telemetry, REST API dumps, and IoT sensor payloads.

💻 EXAMPLE
events_df = spark.read.json("data/web_events.json")

🎯 Mission Objectives

Practice typing production-grade PySpark code for Reading JSON Datasets.

  • Use spark.read.json reader
  • Parse semi-structured JSON records
