### Is your feature request related to a problem or challenge? Hi DataFusion community, I'm currently working on Iceberg-DataFusion write support. `TableProvider::insert_into` provides a handy interface for `INSERT INTO` DML support, but I found that there is no `delete` or `update` interface in `TableProvider`. Ideally, all Iceberg-DataFusion DML support should go through the same layer. In this case, if we want to support `DELETE` and `UPDATE` with DataFusion, we may have to implement a custom planner specifically for those operations, which feels a bit cumbersome to me. If `TableProvider::delete_from` and `TableProvider::update` existed, we could use `TableProvider` as the unified integration point between DataFusion and Iceberg. ### Describe the solution you'd like Support delete or update DML. Would love to learn if there is anything blocking us from doing this. ### Describe alternatives you've considered _No response_ ### Additional context Related issue: https://github.com/apache/datafusion/issues/12406 I'm aware of these [comments](https://github.com/apache/datafusion/blob/aab44fdaaec28fd13b544ccff239c8b8fe6cee2f/datafusion/core/src/physical_planner.rs#L1289-L1297) claiming that DataFusion is a read-only query engine, but I'm assuming they are outdated since we already support insert_into -- This is an automated message from the Apache Git Service.
