Combine Records stage: Advanced section
Use this section to specify options.
You can specify the following options:
- Execution Mode. The stage can run in parallel mode or sequential mode. In parallel mode the input data is processed by the available nodes as specified in the Configuration file, and by any node constraints specified on the Advanced tab. In Sequential mode the entire data set is processed by the conductor node.
- Combinability mode. This is Auto by default, which allows IBM® DataStage® to combine the operators that underlie parallel stages so that they run in the same process if it is sensible for this type of stage.
- Preserve partitioning. The default setting is Propagate. The setting adopts Set or Clear from the previous stage. You can explicitly select Set or Clear. Select Set to request that the next stage in the job attempt to maintain the partitioning.
