Link ordering in Transformer for parallel jobs

Post by mavrick21 »

Hello,

Can anyone please explain to me the use of Link Ordering in Transformer stage and in which scenario this should be used? Will this make sense to use only when Transformer executes in sequential mode? Are links processed in the order specified? Then wouldn't the purpose of parallelism be defeated if this is the case?

I searched this forum but didn't get satisfactory answer.

Thanks for your time.

Link ordering allows you to specify the order in which the output links are processed. This is most useful when you already have an Otherwise/Log output, and want to add a new output link ahead of it. You don't need to disconnect the Otherwise/Log output, you simply re-order in the Link Ordering dialog.
