tMap and Parallel Outputs

Anonymous — Wed, 29 Jun 2016 20:52:11 GMT

Hi -
I wanted to know how tMap handles its outputs, are they serially worked on, or each output pushes data in parallel?
Best Regards,

Hi,
The output from tMap shouldn't be pushed in parallel.
What's your current job situation? Do you want to use tMap component in your workflow?
Best regards

Yes I want to use tMap in the current workflow, could you confirm whether there would be some parallel threads for each output from tMap? or they will be processed sequentially in the order they are connected, which means the data will be pushed to the connected outputs in order one after another rather than parallel push.

The outputs are not parallel. If you take a look at a tMap with 2 or 3 outputs, you will see "order:" then a number. This is the order in which the outputs are cycled. It doesn't mean that you have to wait for all records to pass through an output, but you will not get 2 records outputting at precisely the same time.
