About: - This component is a part of a set of 2 components that allow you to choose between the standard Talend logging framework
(better suited for technical logs),
and the log4J logging framework better suited for business logs (see here : http://logging.apache.org/log4j/1.2/index.html).
- The only parameter to provide to this component is the location of a log4J configuration file
(an XML file, to allow the use of the Asynchronous appender, to optimize performances
(for reference documentation see here : http://wiki.apache.org/logging-log4j/Log4jXmlFormat)
- This component is designed to be used with the tlog4J component.
- This component force the unique initialization of the framework for a job and all his sub jobs,
taking care of concurrency issue (it is thread safe).
- To respect the above statement, you cannot use different log4J configuration between a set of concurrency jobs and subjobs
( you need to have a log4J configuration which contains every appenders / loggers for your differents job).
- This component is startable, and you will need only one per job.
- Thanks to Mathieu Lecarme for the graphics ;-)
- Thanks to OpenWide for saving me a few time to do this ;)

this indicator counts the number of duplicate rows.
It's different from the system indicator called "duplicate count" because it counts the number of duplicate rows, not the number of duplicate values.
