Key Range Partitioning

When you read data by using PowerExchange for SAP Dynamic ABAP Table Extractor, you can configure partitioning to optimize the mapping performance at run time. The partition type controls how the PowerCenter Integration Service distributes data among partitions at partition points.

You can define the partition type as key range partitioning. When you configure key range partitioning, the PowerCenter Integration Service distributes rows of data based on a port or set of ports that you define as the partition key. You can define a range of values for each port. The PowerCenter Integration Service uses the key and ranges to send rows to the appropriate partition.

You can configure key range partitioning for columns of the following data types:

DEC

FLP

INT1

INT2

INT4

INT8

NUMC

Informatica recommends that you do not tune the buffer size because this could lead to performance issues.
