@johanl-db : A big question is where we should apply schema evolution. For MERGE INTO, @szehon-ho did a lot of work to do schema evolution within Spark, so that the behavior is controlled by Spark and all data source will have the same behavior. From this PR, it seems the data source need to implement INSERT schema evolution by its own? -- This is an automated message from the Apache Git Service.
