class dataikuapi.dss.recipe.DSSRecipe(client, project_key, recipe_name)#

A handle to an existing recipe on the DSS instance.

Important

Do not instantiate directly, use dataikuapi.dss.project.DSSProject.get_recipe()

property id#

Get the identifier of the recipe.

For recipes, the name is the identifier.

Return type:

string

property name#

Get the name of the recipe.

Return type:

string

compute_schema_updates()#

Computes which updates are required to the outputs of this recipe.

This method only computes which changes would be needed to make the schema of the outputs of the reicpe match the actual schema that the recipe will produce. To effectively apply these changes to the outputs, you can use the apply() on the returned object.

Note

Not all recipe types can compute automatically the schema of their outputs. Code recipes like Python recipes, notably can’t. This method raises an exception in these cases.

Usage example:

required_updates = recipe.compute_schema_updates()
if required_updates.any_action_required():
    print("Some schemas will be updated")

# Note that you can call apply even if no changes are required. This will be noop
required_updates.apply()
Returns:

an object containing the required updates

Return type:

RequiredSchemaUpdates

run(job_type='NON_RECURSIVE_FORCED_BUILD', partitions=None, wait=True, no_fail=False)#

Starts a new job to run this recipe and wait for it to complete.

print("Job %s done" % job.id)
Parameters:
  • job_type (string) – job type. One of RECURSIVE_BUILD, NON_RECURSIVE_FORCED_BUILD or RECURSIVE_FORCED_BUILD

  • partitions (string) – if the outputs are partitioned, a partition spec. A spec is a comma-separated list of partition identifiers, and a partition identifier is a pipe-separated list of values for the partitioning dimensions

  • no_fail (boolean) – if True, does not raise if the job failed

  • wait (boolean) – if True, the method waits for the job complettion. If False, the method returns immediately

Returns:

a job handle corresponding to the recipe run

Return type:

dataikuapi.dss.job.DSSJob

In order to enable self-joins, join recipes are based on a concept of “virtual inputs”. Every join, computed pre-join column, pre-join filter, … is based on one virtual input, and each virtual input references an input of the recipe, by index

For example, if a recipe has inputs A and B and declares two joins:

  • A->B

  • A->A (based on a computed column)

There are 3 virtual inputs:

  • 0: points to recipe input 0 (i.e. dataset A)

  • 1: points to recipe input 1 (i.e. dataset B)

  • 2: points to recipe input 0 (i.e. dataset A) and includes the computed column

  • The first join is between virtual inputs 0 and 1

  • The second join is between virtual inputs 0 and 2

This method returns a reference to the list of joins, not a copy. Modifying the list then calling DSSRecipeSettings.save() commits the changes.

In this mode, the field “recipe_proto” of this recipe creator is used as-is to create the recipe, and if it exists, the value of creation_settings[“rawPayload”] is used as the payload of the created recipe. No checks of existence or validity of the inputs or outputs are done, and no output is auto-created.

Do not instantiate directly, use dataikuapi.dss.project.DSSProject.new_recipe() instead.

with_existing_output(output_id, append=False)#

Add an existing object as output to the recipe-to-be-created.

The output dataset must already exist.

Parameters:

Create a Python recipe.

Important

Do not instantiate directly, use dataikuapi.dss.project.DSSProject.new_recipe() instead.

A Python recipe can be defined either by its complete code, like a normal Python recipe, or by a function signature.

with_function_name(module_name, function_name, custom_template=None, **function_args)#

Define this recipe as being a functional recipe calling a function.

With the default template, the function must take as arguments:

  • function_name (string) – name of the function

  • function_args (kwargs) – additional parameters to the function.

  • custom_template (string) – template to use to create the code of the recipe. The template is formatted with ‘{fname}’ (function name), ‘{module_name}’ (module name) and ‘{params_json}’ (JSON representation of function_args)
