By default, without a Join set up, in each input table of the input area of the Map Editor, the All rows match model option is selected. This All rows option means that all the rows are loaded from the Lookup flow and searched against the Main flow.

The output corresponds to the Cartesian product of both table (or more tables if need be).

Note: If you create an explicit or an inner Join between two tables, the All rows option is no longer available. You then have to select Unique match, First match or All matches. For more information, see Using Explicit Join and Using Inner Join.
