Build dataset from python

UserBird

Hello,

Is it possible to build a dataset through a python method ?



Cheers,

Yes, you can define a Python recipe with an ouput dataset but no input. Use case could be that you retrieve data from an external API, process it in a Pandas dataframe, and then save it to your output dataset using a dataiku method such as write_with_schema.

The function I was looking for is scenario.build_dataset(). I didn't ask It the proper way

OK great! We have some examples in our doc that may help you: https://doc.dataiku.com/dss/latest/api/public/client-python/index.html#examples

Regarding this particular function (scenario.build_dataset()), is there a list of accepted parameters for the build_mode keyword argument? I saw that RECURSIVE_BUILD is the default parameter, but is there something similar for non-recursive ones?

Here are the available options:
/** Rebuild what is required for dependencies */
RECURSIVE_BUILD,
/** Only rebuild the dataset directly, ignore the state of the dependencies */
NON_RECURSIVE_FORCED_BUILD,
/** Rebuild all recursively, ignore the state of the dependencies */
RECURSIVE_FORCED_BUILD,
/** Recursive build, but only build "missing" datasets, don't refresh out of date ones */
RECURSIVE_MISSING_ONLY_BUILD

Thanks a lot!
