Multiway Merge Join
Description
Multiway Merge Join combines data from three or more sorted input streams into a single output, supporting Inner and Full Outer join types. Use this step when you need to consolidate records from multiple sources simultaneously rather than chaining several Merge Join steps together. It simplifies workflows that require joining more than two datasets on common keys — for example, merging customer, order, and inventory data in a single operation. All input streams must be sorted on their respective join keys before reaching this step.
