…sert and insert overwrite dml (#38115) Support querying rewrite by materialized view when DML such as insert and insert overwrite , into outfile etc. this is default enable, you can disable it by `set enable_dml_materialized_view_rewrite = false` and the `enable_materialized_view_rewrite` is only control DQL. It would not rewrite by materialized view when query sql use external table. If you want rewrite by materialized view when use external table in DML, you should `set enable_dml_materialized_view_rewrite_when_base_table_unawareness = true;` this is default false.
