@rdblue there are some history stories here. Spark supports CREATE TEMP VIEW USING, which creates a special temp view that points to a data source table (e.g. a parquet table, a JDBC table). So INSERT INTO needs to support temp views.
Maybe we can remove CREATE TEMP VIEW USING too, but that needs more discussion.
