What is a key feature of the Union Tool in Alteryx?

The Union Tool in Alteryx is designed to combine multiple data streams into a single output. A key feature of this tool is its ability to accept multiple data streams that share similar structures. This means that the fields across these datasets must have compatible types and names for the Union Tool to function effectively. By aligning fields from different data sources, users can consolidate data for more streamlined analysis and reporting.

This functionality is crucial for users who work with datasets containing repeated measures or parallel data points that need to be joined together in a unified dataset. The Union Tool effectively stacks these data streams on top of one another, making it simple for users to work with large volumes of similar data without needing to individually append or manipulate each source.

The other options describe features that are not applicable or accurate for the Union Tool's primary function. It is specifically built for combining similar datasets rather than handling single streams, sorting records, or appending fields in an unrelated manner.
