Описание: 📌 Data Engineering Zoomcamp 🚀
🗓 Day 27 | Process Behind Spark Dataframe

🔍 Today's Topics:
✅ Anatomy of a Spark Cluster
✅ Group By in Spark
✅ Joins in Spark

📖 Key Takeaways:
📝 Spark Context connects to a cluster, managing resources and tasks.
💡 Spark DataFrames are partitioned for efficient parallel processing.
✨ Group By operations involve data analysis, reshuffling for optimized aggregation.
🚀 Joins in Spark: Various join types, efficient data shuffling, and broadcasting for fast operations.

👨‍💻 Hands-on Practice:
🔹 Explored Spark cluster architecture: master node and executors.
🔹 Performed Group By operations, learning how reshuffling enhances performance.
🔹 Executed joins, understanding the importance of data shuffling and broadcast joins.

📢 Thoughts:
💬 Today’s deep dive into Spark internals revealed the robust architecture and powerful optimizations that make big data processing efficient. Spark truly shines with its distributed capabilities.
