### Is your feature request related to a problem or challenge? Currently, `AggregateExec` does not implement `FilterPushdownPropagation`, which means dynamic filters cannot pass through aggregations. In most cases this is correct behavior - when aggregate functions like `SUM()`, `COUNT()`, `AVG()` are used, filtering rows before aggregation would produce incorrect results. However, there's an important special case: pure grouping operations (`DISTINCT` or `GROUP BY` without aggregate functions). For these operations, it's safe to push filters through because they only de-duplicate data without computing new values. This blocks significant optimization opportunities for queries with DISTINCT or pure GROUP BY on the probe side of inner joins i think ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
