[jira] [Created] (TRAFODION-2316) Implement use of volatile tables for WITH clause and common subexpressions

             Summary: Implement use of volatile tables for WITH clause and common subexpressions
                 Key: TRAFODION-2316
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2316
             Project: Apache Trafodion
          Issue Type: Improvement
            Reporter: Hans Zeller
            Assignee: Hans Zeller


The current implementation of common subexpressions uses a Hive table to store the temporary results. This is not secure. A secure way to do this is to use a volatile table instead. See TRAFODION-2127 for a list of issues with both Hive and volatile tables.
