Talend community forum / Combine two flows to one

seanp_hs · 2012-05-25 23:39:25

Hello -

Is it possible to combine two flows with the same schema into one flow? Each flow is coming from a different datasource and has different data in it, but they have the exact same schema, and I would like to combine them into one flow for later use in a tMap. How can this be accomplished?

Thanks,
-Sean

Take a look at tUnite component.

I've tried using the tUnite and can't connect more than one component to it for input. Anyone manage to do that?

Or have another suggestion for a component to combine flows?

Really? Can you upload a screenshot of the job? There might be a job design problem.

Reading other posts on the forum, it looks like it is not possible to Unite flows that were split out from the same source in the same job. That is the case for me. I have a series of 3 Joins, each one processing the inner Join rejects from the previous. I want to add a transaction code to each of the 3 flows and unite them for further processing. (I throw away the fourth flow). Looks like that can't be done.

Shong, thanks for your very quick answer.

Yes, it is not allowed to unite flows that from th same source, as a workaround, you can output the flows to a temporary files or memory, and then read them back again and unite them in the next subjob.
