transformations:either

## Either table

Between two input datasets (a result of previous transformation and a final state of another table) chooses one that is not empty. If both tables are not empty then it gives preference based on transformation settings.

Use cases

• “If-then” types of workflows. In this scenario the workflow should be organized in a way that makes empty either one table (when a condition is fulfilled) or another (when the condition is NOT fulfilled). Then Either transformation is used to pick a non-empty result dataset of one of these tables. Since both tables can have different sets of transformations it allows applying different transformation logic depending on the condition.
• Insertion of arbitrary datasets at any point of a transformation chain with the help of Sandbox transformation
