zhztheplayer opened a new issue, #7164:
URL: https://github.com/apache/incubator-gluten/issues/7164

   ### Description
   
   Background IO threads (typically used for split preloading) have been 
causing some locking issues since it's not aligned with Spark's threading 
model. For example: https://github.com/apache/incubator-gluten/issues/7161.
   
   And it also causes slow runtime filter: 
https://github.com/facebookincubator/velox/issues/10173.
   
   So we are exploring opportunity to disable it by default until these related 
issues be resolved. Meanwhile would like to here from users for thoughts.
