   # Proposed changes
   
   Issue Number: close #xxx
   
   ## Problem Summary:
   
   In the past, we use generic type for Rule and Job to support do rule based 
transform in Memo for both Plan and Expression. But we do not use memo to do 
expression optimization any more. So generic type is useless for Rule and Job 
and introduces complexity. so we remove generic type from Rule and Job.
