I 'm working on a project for migration of DataStage to Talend and looking for the Talend equivalent of HashFile, indexed binary file that is used for very fast lookup purposes. Does anyone know? Or is there an acceptable workaround or has someone allready created a job that does similar things?
With talend, you haven't need Hash File for lookup : use a tMap, the first input link is the main link, other input are lookups.
by default, tMap use memory to manage lookup. You could check "store on disk" for use tmp file.
