If you have the partitioning option, you can increase the number of partitions in a pipeline to improve session performance. Increasing the number of partitions allows the Integration Service to create multiple connections to sources and process partitions of source data concurrently.
When you create a session, the Workflow Manager validates each pipeline in the mapping for partitioning. You can specify multiple partitions in a pipeline if the Integration Service can maintain data consistency when it processes the partitioned data.
Some partitioning restrictions apply to mapplets.
