🤔 THE QUESTION

How can we combine partition pruning, broadcast joins, salting, and coalesce into an optimized production ETL job?

💡 WHAT IS IT?

Structuring pipelines with best-practice physical layout, broadcast hints, and partition management prevents cluster bottlenecks.

🎯 WHAT IS IT USED FOR?

Enterprise high-throughput data engineering pipelines running on strict SLA windows.

💻 EXAMPLE

df_raw = spark.read.parquet("s3://bucket/sales/").filter(col("sale_date") >= "2026-08-01")
df_optimized = df_raw.join(broadcast(df_stores), "store_id").coalesce(50)
df_optimized.write.mode("overwrite").parquet("s3://bucket/silver_sales/")

🎯 Mission Objectives
