   @PHILO-HE Thanks for the information! I tried with parquet data(nation table 
in TPCH), the details are the following:
   
   ```
   == Fallback Summary ==
   (4) Project: Not supported to map spark function name to substrait function 
name: toprettystring(n_nationkey#23, Some(Asia/Shanghai)), class name: 
ToPrettyString.
   (5) CollectLimit: Gluten does not touch it or does not support it
   
   == Physical Plan ==
   CollectLimit (5)
   +- Project (4)
      +- VeloxColumnarToRowExec (3)
         +- ^ Scan parquet  (1)
   ```
   
   Is the fallback for `Project` expected?
