[jira] [Created] (SPARK-28374) DataSourceV2: Add method to support INSERT ... IF NOT EXISTS

Ryan Blue created SPARK-28374:
---------------------------------

             Summary: DataSourceV2: Add method to support INSERT ... IF NOT EXISTS
                 Key: SPARK-28374
                 URL: https://issues.apache.org/jira/browse/SPARK-28374
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Ryan Blue


This is a follow-up to [PR #24832 (comment)|[https://github.com/apache/spark/pull/24832/files#r298257179]]. The SQL parser supports INSERT ... IF NOT EXISTS to validate that an insert did not write into existing partitions. This requires the addition of a support trait for the write builder, so should be done as a follow-up.
