To identify execution times to verify the effectiveness of your changes, you can use one of these
methods:
Reading the time stamps from the execution console in the Run view. This method allows you to see
the start and end time of each subjob and component in your job, as well as the total execution time
of the job. You can also see the number of rows processed by each component and the status of the
job (success or failure).
Observing the execution times that annotate the flows in the Designer. This method allows you to
see the execution time of each flow (main, lookup, reject, etc.) between components in your job. You
can also see the number of rows processed by each flow and the throughput (rows per second) of
each flow.
You cannot use these methods to identify execution times:
Observing the execution time in the Code view. This method does not show you the execution time
of your job or its components, but only the generated code of your job in Java or Perl. The Code view
is useful for debugging or customizing your code, but not for measuring performance.
Comparing time stamps in Trace Debug mode. This method does not show you the execution time of
your job or its components, but only the values of each column for each row processed by your job.
The Trace Debug mode is useful for tracing data quality or transformation issues, but not for
measuring performance. Reference: Talend Open Studio: Open-source ETL and Free Data Integration
