This tutorial builds a Hudi table on an EMR cluster, then runs upserts and incremental pulls to show how Hudi tracks row-level changes instead of rewriting whole partitions on every update.

It puts Table Formats: Delta vs Iceberg vs Hudi and the merged-storage promise of Lakehouse Architecture: Unifying Warehouse & Lake into practice — one open table format serving both the bulk-rewrite and the incremental-read use case a warehouse-only or lake-only design would need two systems for.
