zhztheplayer opened a new pull request, #10639:
URL: https://github.com/apache/incubator-gluten/pull/10639

   Add a new option `data-gen-features` in gluten-it, to optionally append some 
post operations after the table is generated.
   
   For example, using 
   
   ```
   --data-source=delta --data-gen-features=dv_enabled,10pc_deleted
   ```
   
   To generate a DV-enabled Delta table, where 10% of fact table data is 
deleted.
   
   Another example:
   
   ```
   --data-source=delta --data-gen-features=10pc_deleted
   ```
   
   To generate a regular copy-on-write Delta table , where 10% of fact table 
data is deleted.
   
   The table folder will be named according to the enabled features, for 
example:
   
   `/tmp/tpcds-generated-1.0-delta-partitioned-dv_enabled-10pc_deleted`
