XiaoHongbo-Hope opened a new pull request, #8808:
URL: https://github.com/apache/paimon/pull/8808

   ### Purpose
   
   Filtered data-evolution scans previously materialized projected BLOB 
payloads before applying residual filters and limits. This made filtered-out 
rows still incur payload I/O.
   
   Read eligible BLOB fields as descriptors through merge, filter and limit, 
then materialize only surviving rows. Predicates referencing the BLOB field 
keep the eager path. `read.defer-blob-resolve=false` restores the previous 
behavior.
   
   ### Tests
   
   - `deferred_blob_resolve_test.py`
   - `data_evolution_deletion_vector_test.py`
   - `test_limit_pushdown.py`
   - `DedicatedFormatWriterTest#test_update_blob_column`
   - `DedicatedFormatWriterTest#test_array_blob_column_write_read_and_update`
   - `DedicatedFormatWriterTest#test_map_blob_column_write_read_and_update`
