A deep-dive technical comparison of the three dominant open-source table formats: metadata architectures, ACID guarantees, partition evolution, engine ecosystem support, and write/read latency benchmarks.

A: If your primary compute engine is Databricks, choose Delta Lake with UniForm enabled to gain seamless Iceberg interoperability. For multi-engine data platforms built primarily on Trino, Snowflake, or AWS Athena, Apache Iceberg is the industry standard.
| Dimension | Apache Iceberg | Delta Lake | Apache Hudi |
|---|---|---|---|
| Metadata Spec | Hierarchical Snapshot Manifests | AOT JSON Transaction Log | Timeline Log + File Slices |
| Partition Evolution | Hidden Partitioning (Seamless) | Schema evolution supported | Manual re-partitioning required |
| Engine Agnosticism | Highest (Native Trino/Athena/Spark) | High (UniForm supports Iceberg reads) | Moderate (Spark-centric roots) |
| Compaction Overhead | Low (Metadata manifest rewrites) | Low (Auto-compaction & OPTIMIZE) | Moderate (Compactor service required) |
