Review comment:
actually I came across [INSERT OVERWRITE
DIRECTORY](https://spark.apache.org/docs/latest/sql-ref-syntax-dml-insert-overwrite-directory.html)
which can be mapped to insert_overwrite.
Here is a suggestion w/o using any additional configs:
CTAS -> bulk_insert
Insert into -> insert
INSERT OVERWRITE -> insert overwrite table
INSERT OVERWRITE DIRECTORY -> insert overwrite (partitions)
