OneHouse also has a fantastic iceberg implementation (they're the team behind Apache Hudi) and does a ton of great interop work: https://www.onehouse.ai/blog/comprehensive-data-catalog-comp... && https://www.onehouse.ai/blog/open-data-foundations-with-apac...

HN discussionIt looks like the benchmarks used the latest versions of Delta and Iceberg, but chose a version of Hudi that is over 6 months old. Hudi v0.12.2 is much more advanced than v0.12.0 which the benchmark did not consider. As the Databricks CIDR paper states, and as mentioned in the Onehouse article, Hudi by default is optimized for UPSERTs vs INSERTs and is a 1-line config change that is appropriate for a true apples-app…

HN discussion"A grand don't come for free" It's interesting that they link to (and show graphs from) their earlier post but fail to mention that they had to disable a very large chunk of the features in the checklist to get that performance.

HN discussionInteresting to see they took inspiration from Onehouse on the unified table format Ref dated Feb, 2023: https://www.onehouse.ai/blog/onetable-hudi-delta-iceberg And another big player (SF) is also starting to support additional table formats.
