Why it matters
This feature enables ClickHouse to handle position deletes within Iceberg tables, improving compatibility with the Iceberg format and allowing for more efficient data deletion and management workflows. It solves the problem of supporting Iceberg's position delete semantics natively in ClickHouse, thus enhancing data consistency and correctness when using Iceberg tables.How to use it
Users can leverage this feature by using the Iceberg TableEngine in ClickHouse where position deletes are required. Existing queries and operations involving position deletes in Iceberg tables will now be supported transparently without additional configuration.
