             Summary: LP Bug: 1438445 - Performance regression in git150326 due to hbase-trx
                 Key: TRAFODION-1106
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1106
             Project: Apache Trafodion
          Issue Type: Bug
          Components: dtm
            Reporter: Atanu Mishra
            Assignee: Oliver Bucaojit
            Priority: Critical
             Fix For: 1.1 (pre-incubation)


What we were seeing is that on a 1024 stream OE 30 minute test, the TPM rate would level out.  At around half way through or a little after, the TPM rate started continually dropping every minute.  By the 30 minute mark we were down ~20%.

The git032415 and git032515 builds did not display this rapid degradation in performance.

For these two builds, we did see performance degrade over time, but the TPM rate at the 30 minute mark was consistent with the numbers seen previously.
