🔥 Apache Spark Data Engineering Portfolio

End-to-end PySpark solutions demonstrating production-grade data engineering patterns

Python Apache Spark Azure

📋 Overview

This portfolio showcases hands-on Apache Spark data engineering projects covering large-scale data processing, optimization techniques, and real-world pipeline patterns. Built to demonstrate enterprise-level skills aligned with modern data engineering roles.

🛠️ Projects & Topics Covered

1. ⚡ Local Sort vs. Global Sort in Spark

  • Comparative analysis of sortWithinPartitions() vs sort()
  • Performance benchmarking and shuffle optimization
  • Use cases for each sorting strategy in production pipelines

2. 🔄 ETL Pipeline Patterns

  • Incremental data loading strategies
  • Schema evolution handling
  • Data quality checks and validation layers

3. 📊 Spark SQL & Analytics

  • Window functions for time-series analysis
  • Aggregation optimization with partition pruning
  • Joins: broadcast, shuffle hash, sort merge

4. ☁️ Cloud Integration

  • Azure Data Lake Storage Gen2 (ADLS) integration
  • Delta Lake for ACID transactions
  • Databricks-compatible notebook patterns
