Maximum Parallelism

Maximum Parallelism

Maximum parallelism is valid for the native execution environment. Maximum parallelism refers to the maximum number of parallel threads that process a single mapping pipeline stage. An administrator sets maximum parallelism for the Data Integration Service to a value greater than one to enable mapping partitioning. The administrator sets the maximum parallelism in the Administrator tool.
The default maximum parallelism value for a mapping is Auto. Each mapping uses the maximum parallelism value defined for the Data Integration Service. You can change the default maximum parallelism value to define a maximum value for a particular mapping. When maximum parallelism is set to different integer values for the Data Integration Service and the mapping, the Data Integration Service uses the minimum value.
Default is Auto. Maximum is 64.
For more information about partitioning, see Partitioned Mappings.
