Click the link representing the departitioning step to open its
Component view and click the
Parallelization tab.
The Departition row option has been
automatically selected in the Type
area. If you select None, you are
actually disabling parallelization for the data flow to be handled over
this link. Note that depending on the link you are configuring, a
Repartition row option may become
available in the Type area to repartition a data flow already
departitioned.
In this Parallelization view, you
need to define the following properties:
Buffer Size: the number of
rows to be processed before the memory is freed.
Merge sort partitions: this
allows you to implement the Mergesort algorithm to ensure the
consistency of data.
If required, change the values in the Buffer
Size field to adapt the memory capacity. In this example,
we leave the default value.
