Master deep-dive azure data engineer interview insights with real-world context, covering azure data factory, azure synapse analytics, azure data lake, and other core services.
Master spark session in PySpark, the unified entry point for DataFrames, SQL, and storage; learn to configure memory, parallelism, shuffle, and serialization for ETL and streaming.
Master PySpark window functions row_number, rank, and dense_rank. Partition by region, order by sales, and learn when to use each function for top-performer ranking and duplicate handling.
Master PySpark explode functions to flatten array and map columns in dataframes, using explode, explode_outer, and posexplode to handle nulls and preserve indices.
compare repartition and coalesce in PySpark to manage partitions, showing how repartition triggers a full shuffle for higher parallelism and coalesce reduces partitions before writing optimized output.
Explore practical Spark submit tuning for a 10 GB file by computing 128 MB partitions, setting executor cores and memory, accounting for overhead, and enabling dynamic allocation.
