------------------------------------

             Summary: LP Bug: 1336271 - ESPs are created serially, should be created in parallel
                 Key: TRAFODION-400
                 URL: https://issues.apache.org/jira/browse/TRAFODION-400
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-exe
            Reporter: Apache Trafodion
            Assignee: Apache Trafodion
            Priority: Critical
             Fix For: 0.8 (pre-incubation)


Parallel creation of ESPs was disabled in October '13 to fix a problem with some regression tests failing. It would be good to figure out the specific problem(s), if any, with parallel creation and fix those, so that we don't have to take the performance hit of serial creation. It costs about 15 seconds to fixup a 64 d-o-p plan when ESPs must be started serially, versus ~0.5 seconds if they are started in parallel.
