Pull request overview
This PR enhances Parquet row group filtering by fetching the latest join runtime filters when creating each row group reader, rather than only at the file level. This allows for more efficient data filtering as runtime filters become available during query execution.
Key Changes:
- Added runtime filter update mechanism that is called when creating new Parquet row group readers
- Introduced test coverage to verify that runtime filters are applied across multiple row groups
Reviewed changes
Copilot reviewed 9 out of 11 changed files in this pull request and generated 3 comments.

There was a problem hiding this comment.
The function name cast_set is ambiguous and doesn't clearly convey its purpose. Consider renaming to something more descriptive like set_int_value or using direct casting syntax like static_cast<int>.
Suggested change
| _total_rf_num = cast_set<int>(_local_state->_helper.runtime_filter_nums()); | |
| _total_rf_num = static_cast<int>(_local_state->_helper.runtime_filter_nums()); |

There was a problem hiding this comment.
Moving from _lazy_read_ctx and then assigning back to it on line 416 leaves the source in a moved-from state. Consider copying these values instead of moving, or restructure to avoid the circular dependency.

The default lambda implementation always sets changed to false and returns OK. Consider documenting why this is the default behavior or making it more explicit with a named static function.
