### Feature Request / Improvement Spark added support for MERGE INTO statement that provides a flexible approach to update data, but it's complex in UPSERT case, we can simplify MERGE INTO with default update operation and insert operation like: ``` MERGE INTO prod.db.target t -- a target table USING (SELECT ...) s -- the source updates ``` Same semantics as UPSERT, when match the default primary key, update target field with source row. ### Query engine Spark -- This is an automated message from the Apache Git Service.
