   Hi @Ted-Jiang 
   
   If I read your conclusion corrctly, I think you are saying that the filter added by the filter pushdown rule is remapping the names somehow. Specifically, you are proposing:
   
   ```
               Projection: #ssb@test_udaf_cube_update@17179869183.21 AS LO_SHIPMODE, #ssb@test_udaf_cube_update@17179869183.42 AS _KY_COUNT_DISTINCT_LINEORDER_LO_SUPPKEY_
                 Filter: #LO_SHIPMODE IN ([Utf8("1"), Utf8("2"), Utf8("3"), Utf8("4"), Utf8("5")])  <-- **** This filter should be `#ssb@test_udaf_cube_update@17179869183.21 IN ....`
                   TableScan: ssb@test_udaf_cube_update@17179869183 projection=Some([12, 37]), partial_filters=[#LO_SHIPMODE IN ([Utf8("1"), Utf8("2"), Utf8("3"), Utf8("4"), Utf8("5")])]
   
   ```
