> Components: Security

> We ran into a problem with Submarine's Spark Security for Column Masking
> For example,
> select col_1, col_2 from tbl_1 union select col_3, col_4 from tbl_2
> If masking policies for col_2 and col_4 are different, col_4 will use col_2's
> policy instead of its own
> because col_4 is not in "plan.output"
> we can push down masking project to relation like row filter
