[jira] [Created] (TRAFODION-3041) Repository performance improvement

haolin.song created TRAFODION-3041:
--------------------------------------

             Summary: Repository performance improvement
                 Key: TRAFODION-3041
                 URL: https://issues.apache.org/jira/browse/TRAFODION-3041
             Project: Apache Trafodion
          Issue Type: Improvement
            Reporter: haolin.song
            Assignee: haolin.song


Each query (in watchdog thread)which should be written into repository will be executed once and be sent immediately so that when the statistics limit time is set to 0, the query performance will degrade. It is better to create cache to save queries and execute them as batch size.
