You can configure reader partitions, writer partitions, or both. For reader partitioning, alternative partitioning schemes are available, which cover some or all data sources. For writer partitioning, you must use pass-through partitioning with VSAM or sequential file targets.

Reader and writer partitioning schemes follow standard PowerCenter pipeline partitioning behavior. If you enable either reader or writer partitioning, PowerCenter uses partitions throughout the entire pipeline. If you change the number of partitions at one stage in the pipeline, PowerCenter updates the partition count at all other stages to match. For more information about pipeline partitioning, see the
