---------------------------------
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.
