In the Union page, you can append data from one or more datasets to an existing dataset.

For example, if you have multiple datasets containing transactional data, such as log files, you can use the union operation to join daily or weekly slices of this data into a single dataset.


  • A union operation is different from a join operation. In a join operation, data from two datasets is brought together based on a defined primary key. The type of join determines the columns included in the output. For more information, see Join PanelWindow.

Tip: Depending on the types of operations you need to perform, you should perform your union steps earlier or later in the recipe. See Optimize Job Processing.

In the Search panel, enter union in the textbox.
