Partitioning

Partitioning

When you read data from SAP BW, you can configure partitioning to optimize the mapping performance. The partition type determines how the Data Integration Service distributes data among partitions at partition points.
You can configure the following types of partitioning:
Dynamic partitioning
When you configure dynamic partitioning, the Data Integration Service determines the number of partitions that it must create at run time. It scales the number of partitions based on factors such as the maximum parallelism value defined for the Data Integration Service and the mapping, and the number of CPUs available on the nodes where the mappings run.
For more information about configuring the maximum parallelism value, see the
Informatica Application Services Guide
 and the
Informatica Developer Mapping Guide
.
Fixed partitioning
When you configure fixed partitioning, you must specify the number of partitions that the Data Integration Service must create at run time.
