Function
- In Talend Cloud: A function is an action applied on a row, a column or the whole dataset, such as removing empty rows. In Talend Data Preparation, functions do not modify the original data because they are applied as part of a preparation. Applied functions are recorded, in sequence, into recipes.
- In Talend Data Mapper: A function is a unit of code that accepts a fixed or variable number of arguments and returns a single value. Functions are used to create expressions.
