Ryan Blue created SPARK-23203:
---------------------------------

             Summary: DataSourceV2 should use immutable trees.
                 Key: SPARK-23203
                 URL: https://issues.apache.org/jira/browse/SPARK-23203
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.3.0
         Environment: The DataSourceV2 integration doesn't use [immutable trees|https://databricks.com/blog/2015/04/13/deep-dive-into-spark-sqls-catalyst-optimizer.html], which is a basic requirement of Catalyst. The v2 relation should not wrap a mutable reader and change the logical plan by pushing projections and filters.
