Iterate table

This action is similar to Iterate action, but allows passing a table to an iterated project. The “Iterate table” action has two inputs:

  1. The output of the previous action
  2. The external table it references

The action works as follows: it takes a dataset from another table (2), passes it to the called module or project, and runs it as many times as there are rows in its input dataset (1).

The iterated project should use Input transformation in order to receive the table.

This action allows significantly increasing performance in cases when iterated project had to operate with the same dataset in each iteration.
