When you create a partition point at the Joiner transformation, the Workflow Manager sets the partition type to hash auto-keys when the transformation scope is All Input. The Workflow Manager sets the partition type to pass-through when the transformation scope is Transaction.
You must create the same number of partitions for the master and detail source. If you configure the Joiner transformation for sorted input, you can change the partition type to pass-through. You can specify only one partition if the pipeline contains the master source for a Joiner transformation and you do not add a partition point at the Joiner transformation.
The Integration Service uses cache partitioning when you create a partition point at the Joiner transformation. When you use partitioning with a Joiner transformation, you can create multiple partitions for the master and detail source of a Joiner transformation.
If you do not create a partition point at the Joiner transformation, you can create
n
partitions for the detail source, and one partition for the master source (1:
n
).
You cannot add a partition point at the Joiner transformation when you configure the Joiner transformation to use the row transformation scope.
