Parallel execution of Group Loop

KNIME Analytics Platform
#1

I run a Group Loop to analyze rows of data by a specific grouping. I would like to parallelize this process for efficiancy purposes. I tried bracketing the Group Loop with the Parallel Chunk but it breaks up some groups across chunks and all members of a group need to be processed together. Is there a good way to parallelize the Group Loop process??

Thanks

Worked it out. I bracketed the Parallel Chunk Start with a GroupBy/Ungroup pair. That way my group members are always within one chunk. Worked perfectly.
