[jira] [Created] (SPARK-50319) Reorder BindParameters and ResolveIdentifierClause rules to converge to fixpoint faster

Serge Rielau created SPARK-50319:
------------------------------------

             Summary: Reorder BindParameters and ResolveIdentifierClause rules to converge to fixpoint faster
                 Key: SPARK-50319
                 URL: https://issues.apache.org/jira/browse/SPARK-50319
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 4.0.0
         Environment: The current relative order  # ResolveRelations
 # ResolveIdentifierClause
 # BindParameters


These rules interact in exactly the opposite way as they are listed:
* BindParameters always operates on leafs
* ResolveIdentifierClause turns constant expressions (typically parameters) into UnresolvedRelations
* ResolveRelations is needed to progress resolved identifier clauses
 
We propose to move BindParameters and ResolveIdentifierClause up.
            Reporter: Serge Rielau
