Dataship-Join Requirements for Increased Performance

Dataship-Join Requirements for Increased Performance

The dataship-join optimization method does not always increase performance. The following factors affect mapping performance with dataship-join optimization:
  • The Joiner transformation master source must have significantly fewer rows than the detail source.
  • The detail source must be significantly large to justify the optimization. If the detail source is not large enough the Data Integration Service finds it is faster to read all the data from the master and detail source without applying the dataship-join optimization method.
