Github user gatorsmile commented on the issue: https://github.com/apache/spark/pull/16594 Let us do some research how the other RDBMSs are doing it? For example, Oracle ``` SQL> explain plan for select * from product; Explained. SQL> select * from table(dbms_xplan.display); PLAN_TABLE_OUTPUT ----------------------------------------------------- Plan hash value: 3917577207 ----------------------------------------------------- | Id | Operation | Name | Rows | Bytes | ----------------------------------------------------- | 0 | SELECT STATEMENT | | 15856 | 1254K| | 1 | TABLE ACCESS FULL | PRODUCT | 15856 | 1254K| ----------------------------------------------------- ```
