Feeds the parallel execution processes with the threads generated by tPartitioner.

Note that Talend Studio also enables the automatic implementation of parallelization across a Job without use of the parallelization components and Talend recommends using that approach. For further information, see Enable parallelization of data flows. 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 receives parallel threads from tPartitioner and sends those threads to the following components for parallel execution.

This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.
