https://community.qlik.com/t5/Talend-Studio/Talend-Job-Memory-Usage/m-p/2280315#M55210 All, <BR />I would like to know how much memory allocated for a newly created job in Talend. <BR />Where the "Aggregate" , "Sort" and "Join" operation will be performed? I mean which memory i.e Disk or Temporary ? <BR />Is it advisable to use "Aggregate" to do aggregate operation in Talend? In Datastage, it will be considered as least option to choose to do aggregate operation.
