ggjh-159 opened a new issue, #12457:
URL: https://github.com/apache/gluten/issues/12457

   ### Description
   
   gluten-flink initializes velox4j via `Velox4j.initialize()` in 
`TaskManagerRunner`. velox4j historically only shipped a `SPARK` preset, so 
gluten-flink inherited Spark function semantics.
   
   velox4j now adds a sibling `FLINK` preset (bigo-sg/velox4j#54), backed by 
`velox/functions/flinksql/`. The default remains `SPARK`, so gluten-flink must 
explicitly opt in via `Velox4j.configure(Preset.KEY, Preset.FLINK)` before 
`Velox4j.initialize()`.
   
   ### Gluten version
   
   main branch
