Pipeline Partitioning

Pipeline Partitioning

When running sessions, the PowerCenter Integration Service process can achieve high performance by partitioning the pipeline and performing the extract, transformation, and load for each partition in parallel. To accomplish this, use the following session and PowerCenter Integration Service configuration:
  • Configure the session with multiple partitions.
  • Install the PowerCenter Integration Service on a machine with multiple CPUs.
You can configure the partition type at most transformations in the pipeline. The PowerCenter Integration Service can partition data using round-robin, hash, key-range, database partitioning, or pass-through partitioning.
You can also configure a session for dynamic partitioning to enable the PowerCenter Integration Service to set partitioning at run time. When you enable dynamic partitioning, the PowerCenter Integration Service scales the number of session partitions based on factors such as the source database partitions or the number of nodes in a grid.
For relational sources, the PowerCenter Integration Service creates multiple database connections to a single source and extracts a separate range of data for each connection.
The PowerCenter Integration Service transforms the partitions concurrently, it passes data between the partitions as needed to perform operations such as aggregation. When the PowerCenter Integration Service loads relational data, it creates multiple database connections to the target and loads partitions of data concurrently. When the PowerCenter Integration Service loads data to file targets, it creates a separate file for each partition. You can choose to merge the target files.
