Covers partitions and how to manage them with repartition() and coalesce(), shuffles and why they're expensive, join optimization techniques including broadcast joins, reading execution plans with explain(), caching strategies, Parquet partitioning for efficient reads via partition pruning, and why built-in functions outperform Python UDFs. Includes a complete worked example combining all concepts with an annotated execution plan. ## Full article daily.dev links to this article rather than hosting it.
