+ | - The output of the previous action | ||
+ | - 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 [[transformations: | ||
+ | |||
+ | This action allows significantly increasing performance in cases when iterated project had to operate with the same dataset in each iteration. | ||

- | This transformation allows significantly increasing performance in cases when iterated project had to read the same file in each iteration (in previous versions of EasyMorph). Now such file can be read once and then passed to an iterated project in memory. |
