    Info

    NOTE: This propagation does not apply to:

    1. Datasets that are created from the generated output of the dataset. Since the new dataset is the product of an executed job, it no longer has any connection to the changes in the source dataset. If you wish to propagate those changes, however, you can re-run the job and write out a new dataset. See Publishing Dialog .

    2. Copies of the dataset. Dataset copies are independent objects. 


     

Implications:

In Release 3.1.2 and earlier, multi-dataset operations, such as union, join, and lookup, were executed on a snapshot of the other dataset. For example, if dataset A performed a lookup into dataset B, the application internally performed a snapshot of dataset B and used the snapshot for completing the lookup. This snapshot is maintained separately.

...

When you first open a dataset in the Transformer page in Release 3.2, a new random sample is automatically generated for you. Also, given the larger sample size in Release 3.2, your entire dataset may be displayed in the Transformer page.
