If the volume of data grows or you add more CPUs, you might need to adjust partitioning so the session run time does not increase. When you use dynamic partitioning, you can configure the partition information so the Integration Service determines the number of partitions to create at run time.
The Integration Service scales the number of session partitions at run time based on factors such as source database partitions or the number of nodes in a grid.
If any transformation in a stage does not support partitioning, or if the partition configuration does not support dynamic partitioning, the Integration Service does not scale partitions in the pipeline. The data passes through one partition.
Complete the following tasks to scale session partitions with dynamic partitioning:
Set the partitioning.
The Integration Service increases the number of partitions based on the partitioning method you choose.
Set session attributes for dynamic partitions.
You can set session attributes that identify source and target file names and directories. The session uses the session attributes to create the partition-level attributes for each partition it creates at run time.
Configure partition types
. You can edit partition points and partition types using the Partitions view on the Mapping tab of session properties.
Do not configure dynamic partitioning for a session that contains manual partitions. If you set dynamic partitioning to a value other than disabled and you manually partition the session, the session is invalid.
