zhangliang created TRAFODION-2207:
-------------------------------------
Summary: Phenomenon of odb copy with parameter parallel is not
consistent with the document description
Key: TRAFODION-2207
URL: https://issues.apache.org/jira/browse/TRAFODION-2207
Project: Apache Trafodion
Issue Type: Bug
Components: db-utility-odb
Reporter: zhangliang
Priority: Minor
As the odb user guide ODB user guide.pdf says
"odb uses as many threads as the parallel argument to extract data from
partitioned source tables PLUS an equivalent number of threads to
write to the target table."
It mean if parallel is 4, odb will start 8 thread, 4 for extract and 4 for load.
But in practice, odb will start triple threads of parameter parallel if not
limit with -T. It is not consistent with document.
Maybe we should update our document.
