For each row this step iterates over the lists of IDs in one or more target columns, and if a ID exists also in the source column, the corresponding rows will be connected.

Note that while this step allows multiple input columns to be used as link targets, it does not allow for the specification of link weights. See the step link_rows for creating weighted networks. All link weights will be set to 1.0 by default. But see the weight_factor param to specify another constant instead.

weight_factor
number
default: "1.0"

Multiply link weights by this number.
