Ulrich Kramer created CALCITE-6249:
--------------------------------------

             Summary: RelNode::estimatedRowCount should not be used in 
computeSelfCost
                 Key: CALCITE-6249
                 URL: https://issues.apache.org/jira/browse/CALCITE-6249
             Project: Calcite
          Issue Type: Bug
            Reporter: Ulrich Kramer


{{RelNode::estimatedRowCount}} is still used in many place inside 
{{computeSelfCost}}

It it should be possible to implement the estimation of the row count 
completely outside Calcite, these calls should be replaced by 
{{mq.getRowCount(rel)}}.
