zhztheplayer opened a new pull request, #5824:
URL: https://github.com/apache/incubator-gluten/pull/5824

   1. In RAS, reuse transition facilities added in 
https://github.com/apache/incubator-gluten/pull/5767 to do convention 
enforcement.
   2. Rename RAS's `Convention` and relevant classes to new names starting with 
`Conv`.
   3. New trait `KnownChildrenConventions` to allow user-defined children 
batch-type requirements for a specific `SparkPlan` node. To better understand 
the need of this, one can think about `convention` as something similar to an 
existing physical property vanilla Spark already implements, say `ordering`, 
`SparkPlan` has both method `outputOrdering` and `requiredChildOrdering` to 
define the ordering and allowed children's orderings for a single plan node.
   4. Other essential code refactors.
