Thanks @unikdahal
I prob missing something, what is `DataFusion-native source for pre-planned
tasks`?
My understanding DataFusion still talking to iceberg through iceberg-rs,
ArrowReader
```
DataFusion (SQL, DataFrame, optimizer)
└─ CatalogProvider / SchemaProvider / TableProvider / ExecutionPlan
└─ datafusion-iceberg: adapters plus custom plan nodes
└─ iceberg-rust: Catalog, TableScan, ArrowReader, writers,
Transaction
└─ FileIO (StorageFactory, e.g. OpenDAL) → S3, GCS, local
```
