We are also interested in the comparison of Hudi, Delta Lake, and Iceberg. We have recently added support for Hudi and Delta Lake; you can check here: https://clickhouse.com/docs/en/engines/table-engines/integrations/deltalake https://clickhouse.com/docs/en/engines/table-engines/integra... It is a read-only implementation: ClickHouse can read and process the external data in the Hudi or Delta Lake format. Apache Iceberg is pending. There is no good C++ library for it. But at least the overall structure is simple, as it is not hard to implement it. The overall principle - whatever data format it is, ClickHouse should support it in a fast, stable, and ALWAYS CORRECT manner. If you have more experience to share, please do it.
