What you are doing is filtering application... you can use tfilterrow component. One more thing is that you are not receiving memory error, you can also think ff Hash components to replicate data to two filter row components and write data independently to your output device. <BR />Vaibhav Mon, 15 Sep 2014 15:31:47 GMT Anonymous 2014-09-15T15:31:47Z https://community.qlik.com/t5/Talend-Studio/How-to-use-parallelization-of-data-flows/m-p/2360444#M125021 Hi, <BR />I tried to test the new feature called "parallelization of data flows".&nbsp; <BR />Consequently, I created the Talend job below. <BR />tFileInputDelimited with 5000000 rows, <BR />| row1 <BR />tMap with a little transformation, <BR />| row2 <BR />tFileOutputDelimited <BR />For row1 : <BR />« Nombre de process enfants » = 3 (I have 4 processors) <BR />« QUEUE_SIZE » = 5000. <BR />Pour row2 : <BR />« Merge sort partitions » = yes <BR />« QUEUE_SIZE de out1 » = 5000 <BR />Unfortunatly, my results are really bad : the new fonctionality increase the processing time by 10 seconds. <BR />On the internet, I only saw examples of this feature with a tSortRow component.&nbsp; <BR />Could you tell me if it is possible to implement this new feature with other Talend components ? <BR />Regards.
