Outputs of the parallel execution results, depending on tDepartitioner.
Note that Talend Studio also enables the automatic implementation of parallelization
across a Job without use of the parallelization components and we recommend using that
approach. For further information, see the section describing how to enable
parallelization of data flows of the Talend Studio User Guide. However, if you
need to understand how to use these specific parallelization components, bear in mind
that the parallelization components work closely with each other to accomplish parallel
execution on given processes: the tPartitioner
component dispatches the input records into a specific number of threads; the tCollector component sends these threads to its following
components for parallel execution; the tDepartitioner
component regroups the outputs of the processed parallel threads; the tRecollector component captures the output of a given
tDepartitioner component and sends the captured
data to the next component.
This component captures and outputs the parallel execution results
that a given tDepartitioner has
tRecollector Standard properties
These properties are used to configure tRecollector running in the Standard Job framework.
tRecollector component belongs to the Orchestration family.
