Forming Partition Groups Without Resource Requirements

Forming Partition Groups Without Resource Requirements

If the session has more than one partition, the DTM forms partition groups based on the partitioning configuration.
For example, you configure a session with two partitions. The DTM creates partition groups for the threads in each partition, and the Load Balancer distributes the groups to two nodes. Partition group 1 runs on Node 1, and partition group 2 runs on Node 2.
The following image shows two partition groups for a session that contains two partitions:
One session is configured with two partitions. Each partition contains a reader, a transformation and a writer. The DTM puts the partitions into partition groups. The Load Balancer assigns Partition group 1 to run on Node 1 and Partition group 2 to run on Node 2.
