geruh opened a new pull request, #2918:
URL: https://github.com/apache/iceberg-python/pull/2918

   Related to #2255.
   
   # Rationale for this change
   
   This PR is a piece of the existing DFI PR in #2255. However, this rips out 
the existing delete->data matching behavior for deletes and indexes them for 
efficient lookup.
   
   The previous implementation:
   1. Scanned all delete files with sequence number >= data file's sequence 
number
   2. Created a new `_InclusiveMetricsEvaluator` instance for each data file
   3. Evaluated every candidate delete file against the data file's path
   
   Now we extend this workflow with a `DeleteFileIndex` that:
   - INdexes path specific DVs 
   - Indexes partition-scoped deletes by (spec_id, partition record)
   - Uses bisect_left for sequence number filtering 
   
   This aligns with the Java implementation of the 
[DeleteFileIndex](https://github.com/apache/iceberg/blob/main/core/src/main/java/org/apache/iceberg/DeleteFileIndex.java),
 following the python infra.
