   > I think the key point is the design of MergingSnapshotProduder, which 
contains a lot of indices to speed up the confliction check.
   
   I think you meant 
[`DeleteFileIndex`](https://github.com/apache/iceberg/blob/1cea23eda51c9b9ddcfb88dd499b1fd14f3bf3b3/core/src/main/java/org/apache/iceberg/MergingSnapshotProducer.java#L624-L625)
 in java implementation and the `conflictDetectionFilter`. In rust's 
[`DeleteFileIndex`](https://github.com/apache/iceberg-rust/blob/main/crates/iceberg/src/delete_file_index.rs#L56),
 we don't allow filter to be pushed down at this point, so I didn't include 
that change. 
   
   In the future, we could store the filter in snapshot operations like 
`RowDeltaAction` and pass the filter to 
`SnapshotValidator::validate_no_new_deletes` easily. 
   
   The current implementation won't block that change, we will only need to 
change the API in `SnapshotValidator` after adding conflict_detecting_filter 
support to `DeleteFileIndex`
