The following rules apply to using dynamic partitioning with different partition types:
- Pass-through partitioning. If you change the number of partitions at a partition point, the number of partitions in each pipeline stage changes. If you use pass-through partitioning with a relational source, the session runs in one partition in the stage.
- Key range partitioning. You must define a closed range of numbers or date keys to use dynamic partitioning. The keys must be numeric or date datatypes. Dynamic partitioning does not scale partitions with key range partitioning on relational targets.
- Database partitioning. When you use database partitioning, the Integration Service creates session partitions based on the source database partitions. Use database partitioning with Oracle and IBM DB2 sources.
- Hash auto-keys, hash user keys, or round-robin. Use hash user keys, hash auto-keys, and round-robin partition types to distribute rows with dynamic partitioning. Use hash user keys and hash auto-keys partitioning when you want the Integration Service to distribute rows to the partitions by group. Use round-robin partitioning when you want the Integration Service to distribute rows evenly to partitions.
