Subject [jira] Created: (DERBY-741) row estimates from btree code can sometimes return more row than exist in table

row estimates from btree code can sometimes return more row than exist in table
-------------------------------------------------------------------------------

         Key: DERBY-741
         URL: http://issues.apache.org/jira/browse/DERBY-741
     Project: Derby
        Type: Bug
  Components: Store  
    Versions: 10.0.2.0, 10.0.2.1, 10.1.1.0, 10.1.1.1, 10.1.1.2, 10.1.2.0, 10.1.2.1    
    Reporter: Mike Matrigali
 Assigned to: Mike Matrigali 
    Priority: Minor


In BTreeCostController the recursive row estimate can sometimes return more rows than exists
in the table.  In Sane server an ASSERT would be thrown.  Simple change is to just always
make the max estimation be all the rows in the table.
