Hi there,
I am intending to work more often with the datasets, but not sure if there is a way to retrieve specific files from a uploaded dataset. I saw I can retrieve chunks of data, but not sure how that would work with a dataset of parquet files. If I have a parquet with my data for each day, how could I store it to make sure I can retrieve a single day only at some point? Is it possible?

Apparently found out a solution:
dataset_zip = dataset._task.artifacts['data'].get() will return the path to the zip file containing all the files (that will be downloaded to the local machine)
after that:
import zipfile zip_file = zipfile.ZipFile(d, 'r') files = zip_file.namelist()retrieving the names of the files
unzip using
import os os.system(f'unzip {dataset_zip}') # in this case to your script directoryand using the files list one can them open them selectively

Could you supply any reference of this dataset containing other datasets? I might have skipped that when reading the documentation, but I do not recall seeing this functionality.

Is there a better way?

ShallowGoldfish8 , I think the best would be storing them as separate datasets per day and then having a "grand" dataset that includes all days and new days are being added as you go.

What do you think?

Since the "grand" dataset will inherit from the child versions you wouldn't need to have data duplications
