A deep-dive optimization guide for Apache Iceberg analytics workloads covering the full stack: query planning internals (4-stage metadata pipeline), partition design, file sizing, sort/Z-order strategies, metadata lifecycle management, delete file economics, multi-engine cost routing, and continuous maintenance sequencing. Includes production benchmarks showing 9× query speedup from file consolidation alone, and guidance on ordering maintenance operations (snapshot expiration → orphan cleanup → compaction → manifest rewrite → statistics). Also covers multi-engine routing economics showing significant cost differences between DuckDB, Trino, Snowflake, and Athena for the same Iceberg tables.
