Multiway Merge Join
Multiway Merge Join
Description
This step allows to join from multiple streams and supports INNER and FULL OUTER joins.
Note: The Merge Join step only allows to do this for two streams. This can be inefficient, and hard to parallelize. The Multiway Merge Join step showed performance improvements on different use cases.
Metadata Injection Support (7.x and later)
All fields of this step support metadata injection. You can use this step with ETL Metadata Injection to pass metadata to your transformation at runtime.
