Notes

The default value for this property is 5. The value of 1 is not permitted.

This property provides a suggestion to the data flow engine about the number of threads to use. However, the engine will not use more threads than it needs, regardless of the value of this property. The engine may also use more threads than specified in this property, if necessary to avoid concurrency issues.

For more information, see Plan d'exécution et allocation de mémoire tampon.

For a brief discussion of this property and related properties that can be used to optimize the performance of the Data Flow task, see Fonctionnalités de performances de flux de données.
