Apache Iceberg vs. Delta Lake

Feature Comparison

When comparing Apache Iceberg to Delta Lake, several distinct features emerge. Delta Lake, developed by Databricks, is another open-source storage layer that brings reliability to data lakes. However, there are key differences:

• Schema Evolution: Both formats allow you to evolve schemas.
• Partitioning: Iceberg's Hidden Partitioning allows for easily manageable advanced partitioning, while Delta Lake has a feature called Generated Columns that enables similar ergonomics, it doesn't reduce the amount of data storage in the same way Iceberg's hidden partitioning does. Only Apache Iceberg allows for partition evolution.
• Time Travel: Both Iceberg and Delta Lake support time travel queries, but Iceberg, when working with a Nessie catalog, can use its catalog versioning features to easily time travel across multiple tables.

Performance and Scalability

Apache Iceberg is designed for high performance and scalability. Its architecture supports efficient data reads and writes, reducing latency and improving query performance. OSS Delta Lake, doesn't have the same bells and whistles as the proprietary features available on the Databricks allow, so adopting Delta Lake means accepting a strong commitment and lock-in to the Databricks platform.
