      Description

      When writing to a FileFormat datasource, bucket spec and partition columns are passed into InsertIntoHadoopFsRelationCommand: https://github.com/apache/spark/blob/v3.0.0/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala#L474-L475.

       

      However, from what I can tell, the RelationProvider API does not have a way to pass in these: https://github.com/apache/spark/blob/v3.0.0/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala#L511-L513.
