Change a recipes engine using the API

NN

Hi Everyone,
I know we can get the selected engine details of a recipe using the API.
but is there a way to change the engine of the recipe as well using the API ?

Any suggestions are welcome Thanks..

Hi @NN
,

It is possible to change the engine used by a recipe by changing the value of `engineType` in that recipe's settings.

Here's an example (assume the `engineType` is 'DSS' and I want to change it to 'SQL' via the API):

import dataikuapi

host = DSS_HOST
apiKey = DSS_API_KEY
client = dataikuapi.DSSClient(host, apiKey)

proj = client.get_project("COMMUNITY_24974")
recipe = proj.get_recipe("compute_orders_copy_filtered")

settings = recipe.get_settings()
settings.raw_params['engineType']='SQL'
settings.save()

Note: a recipe may be able to use only a subset of engines. To determine which engines are eligible to be used by a recipe check the output of `recipe.get_status().get_engines_details()`. If an engine has `'isSelectable': True` then that engine can be used for that recipe.

Thank you,
Mike

Thanks @MikeG

Hi Dataiku Team,

I am able to change the engine of prepare recipes using the code. But it fails for other recipes like join and group. The error I get is shown below:

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)
<ipython-input-99-f75ef26b38e9> in <module>
      1 settings = recipe.get_settings()
----> 2 settings.raw_params['engineType'] = 'DSS'
      3 settings.save()

/opt/dataiku-dss-12.5.1/python/dataikuapi/dss/recipe.py in raw_params(self)
    527         :rtype: dict
    528         """
--> 529         return self.recipe_settings["params"]
    530 
    531     def _payload_to_str(self):

KeyError: 'params'

Can anyone help me resolve this issue?

Hi,

For join recipes, you should use the below:

settings.get_json_payload()['engineType'] = 'DSS'
settings.save()

Best.
