public class PushInequalityFilterExpressionBelowJoinRuleSet extends Object
Rule that transform plan like 
 
  filter: expr(l) > expr(r)
      join
          probe(l)
          build(r)
to 
 
  filter: expr(l) > expr_r
      join
          probe(l)
          project (expr_r := expr(r))
              build (r)
This rule allows dynamic filtering to be applied for inequality join node. Additionally, optimized execution of inequality join is performed when equi conditions are also present.
