---------------------------------------

             Summary: Bucketing and Partitioning information are not passed on 
to non FileFormat datasource writes
                 Key: SPARK-32544
                 URL: https://issues.apache.org/jira/browse/SPARK-32544
             Project: Spark
          Issue Type: Improvement
          Components: Input/Output
    Affects Versions: 3.0.0
            Reporter: Rahij Ramsharan


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].
