Rules and Guidelines for Creating Partition Groups

Rules and Guidelines for Creating Partition Groups

The Integration Service uses the following rules and guidelines to create partition groups:
  • The Integration Service limits the number of partition groups to the number of nodes in a grid.
  • When a transformation is partitionable locally, the DTM process forms one partition group for the transformation threads, and runs that group in one DTM process. The following transformations are partitioned locally:
    • Custom transformation configured to partition locally
    • External Procedure transformation
    • Cached Lookup transformation
    • Unsorted Joiner transformation
    • SDK Reader or Writer transformation configured to partition locally
