🤔 THE QUESTION

How can we construct an enterprise file export pipeline with snappy compression, dynamic partition overwrite, and file size capping?

💡 WHAT IS IT?

Combining compression settings, dynamic partition overwrite, maxRecordsPerFile, and partitioning into a production write stage.

🎯 WHAT IS IT USED FOR?

Publishing gold-layer lakehouse tables to cloud storage with guaranteed performance and storage SLA compliance.

💻 EXAMPLE
spark.conf.set("spark.sql.sources.partitionOverwriteMode", "dynamic")
df_gold = df.withColumn("year", year("transaction_date")).withColumn("month", month("transaction_date"))
df_gold.write.partitionBy("year", "month").option("maxRecordsPerFile", 500000).mode("overwrite").parquet("s3://lakehouse/gold/financial_ledger/")

🎯 Mission Objectives
