Export very large dataset (million or row) in CSV as chunks

Is it possible in DOMO using python or postman to export whole dataset but break files(CSV/Excel) so we can have 5 million rows in each exported file.

    Hi @user094816

    I don't believe Domo's API supports pagination / chunking data. You could utilize the API to read the entire dataset and then use your python script to do the splitting logic yourself.

  • Hi @GrantSmith , Thank you for your feedback. Since domo is slow while exporting data from cards (applying filer of date range to reduce number of rows < 10 ML) for 2 reasons

    1) data is very huge

    2) Many filters applied on card

    I have solved 2nd option and added all filters on ETL itself to reduce the data and generated a new dataset.

    Now I am looking for export this huge dataset 104 M rows with 38.5 GB data size. What is the best approach?

    I tried to filter and export from UI in DOMO Dataset, but it's not exporting filtered rows from dataset.

    either use dataset views to construct filtered views of your dataset, or use the domo cli https://knowledge.domo.com/Administer/Other_Administrative_Tools/Command_Line_Interface_(CLI)_Tool#section_34, to query-data or export-data and create filtered exports.
