   We do something along these lines. Not for security per-se so I'm not going 
to vouch for it being secure but I think in principle it is:
   
   ```rust
   fn register_filtered_view(
       &self,
       ctx: &SessionContext,
       kind_field: Option<&str>,
       table_name: &str,
       provider: Arc<dyn TableProvider>,
   ) -> DataFusionResult<()> {
       let mut df = ctx.read_table(provider)?;
       df = apply_filters(ctx, df, &self.filters, table_name)?;
       ctx.register_table(table_name, df.into_view())?;
       Ok(())
   }
   ```
