Apache Iceberg vs Delta Lake vs Apache Hudi

Are table format wars ⚔️ over yet? Yes, but not in the way you expect. Delta Lake seems placed in the rearview mirror. Apache Hudi? The Hudi community has also moved on from format wars as it recently introduced native Iceberg format support. A table “format” is simply a metadata specification to define tables. It is a means to an end and if you unpack the layers, you will find what is defined as a “table format” is actually a pretty thin layer 🧠

In 2025 it’s no longer about what “table format” you should be using, and now it's a question of how are you managing your “database on the lake”. The Hudi community calls this a DLMS - “Data Lakehouse Management System”.

Our long-running comparison article, first published in 2022 is now freshly updated for October 2025 including features from the latest project releases. It remains the most comprehensive resource to compare Hudi, Iceberg and Delta, but this time, with a fresh new lens.

At Onehouse, our platform excels across all 3 Hudi, Iceberg and yes, even Delta. So while it doesn’t matter too much to us which one you choose, it might still matter to you.
