Advance Designer Certificate Exam Step 9

timchen

Hello,

I am working on creating the flow on Dataiku Advance Designer Certificate Assessment.

I am having an issue with redispatch

From the hands-on tutorial, there is an option for Redispatch:

However, in the flow I am creating, I didn't see this option

Did I miss any steps or I am thinking to the wrong step.

Can you please guide me how to solve step #9?

(I have confirmed from step 8 I have 67 rows in the dataset 2010)

I am on version 9.0.2

Thank you!

Best,

Tim

Hi Tim,

The Redispatch option will show up only after you add partitions to the output dataset. The steps would be :

1. Create the Sync recipe, go back to the flow.

2. Edit the output dataset partitions go to Settings -> Partitioning -> Activate Partitioning, Add the required dimension and Save

3. Got back the Sync recipe and the Redispatch option should appear.

Hello Alex,

Thanks for getting back to me. Can you give me some hint about the pattern and name.

I don't know how to get the setting align with the requirement.

Thank you!

Hi Tim,

The instructions for step 9 mention :

Using a Sync recipe, redispatch the data in the Online_Retail_to_2010 dataset into partitions given by the stock_code (a discrete identifier). That is, create partitions for each stock code.

So you should end up with a dataset partitioned by the discrete identifierr stock_code. Hope this helps!

Additionally, there is an example here: https://knowledge.dataiku.com/latest/kb/data-prep/partitions/partitioning-redispatch.html that may be helpful in understanding this concept.
