Using output of tmap as lookup for another tmap

Anonymous — Fri, 18 Nov 2016 04:21:21 GMT

Hi! I'm new to Talend. I was just wondering if the following is possible:
tFileInputDelimited_1->tmap1-> perform some rank function
->tmap2 -> look up output of rank function
The tool is not letting me connect the output of the rank function to tmap2. Any help is appreciated. Thanks in advance!

Hi,
Talend don't support for "Circle" in work flow.
Could you please have a look at document about:https://community.talend.com/t5/Design-and-Development/Can-I-create-a-Job-with-multiple-paths-from-a-single-source-to/ta-p/21653
Hope it will help.
Best regards
Sabrina

I do believe that it IS possible to connect the Output from one tMap component as the Input for another tMap component.
The actual specific format / content of your tMap Output might affect its Input connection to the next tMap component, but in principle, it's certainly possible (I've just done it).

Sabrina,
Thanks for the information. I've decided to use tHashOutput and tHashInput as a work around. Question, for the same job, I have about 6 input file. When running in my laptop is there a way for all 6 file to read simultaneously?
