Suppress GroupBy warning "No grouping column included"?

KNIME Analytics Platform
#1

I am using GroupBy to aggregate complete tables (often as part of loops, making said tables quite small) and I’m seeing many repeats of

“WARN GroupBy No grouping column included. Aggregate complete table”

In my KNIME console. Is there a way to have this warning not output to the console? I’m developing this workflow for someone else to eventually use and seeing thousands of repeats of this message would not be helpful for them.

thank you

Hi there,

I’m afraid unless you put your Log Level for Console to Error that this is not possible. But maybe it should be classified as a INFO instead.

As a workaround you can add column with Constant Value Column node before GroupBy. Use that column as grouping column. After GroupBy drop that column.

Br,
Ivan
