Hello forum,

I am new to use KNIME. Here is my problem, as shown below:

I have 71 files, when I use this workflow, it only reads one file in one loop. one file takes 10 min, so the total time is 71x10=710 min, above 11 hours.

Therefore, I am wondering there is a parallel workflow to process this kind of data? for example, 10 files could be processed in one loop, that will only take about 2 hours.

Thanks a lot!

Bests,
