Pushdown might be not a good word to use here, if there is a better wording let me know. The Snowflake doc provides a good case: https://docs.snowflake.com/en/user-guide/views-secure#how-might-data-be-exposed-by-a-non-secure-view. A filter to get additional information out of a view like `1/iff(color = 'Purple', 0, 1) = 1` is what we are trying to have different ways to handle. In the latest EMR Spark security features we distinguish those concepts when evaluating a view in an execution plan. So to have a good integration with Iceberg view, we would like to introduce this concept. -- This is an automated message from the Apache Git Service.
