Dataship-Join Optimization Rules and Guidelines

Dataship-Join Optimization Rules and Guidelines

The Data Integration Service can apply dataship-join optimization to a Joiner transformation if the transformation meets the following requirements:
  • The join type must be normal, master outer, or detail outer.
  • The detail pipeline must originate from a relational source.
  • If the mapping uses target-based commits, the Joiner transformation scope must be All Input.
  • The master and detail pipelines cannot share any transformation.
  • The mapping cannot contain a branch between the detail source and the Joiner transformation.
  • The Data Integration Service fails to apply the dataship-join optimization method if the database which contains the detail side of the join is an IBM DB2 database that does not support Unicode encoding.
