KNIME Base Nodes version 4.0.2.v201909251340 by KNIME AG, Zurich, Switzerland

Group loop start, each iteration processes another group of rows. The column(s) to group on need to be specified.

Sorting can be switched off if input data table is already properly sorted based on the columns to group on. If sorting is switched off, but input table is not properly sorted execution will be canceled.
