Python users with data in external object storage can transfer the data to or from the Analytics Database using the Native Object Store feature in teradataml. External object storage includes AWS S3, Google Cloud Storage and Azure Data Lake Storage Gen2, and so on.

The Native Object Store feature in teradataml provides ability for Python users to:
  • Search and query CSV, JSON, and Parquet format datasets located on external object storage platforms.
  • Write data stored on Vantage to external object storage platforms.

The ReadNOS and WriteNOS APIs in teradataml enable reading and writing datasets to external object storage platforms.

  • Import these functions only after establishing the connection to Vantage. Importing these functions before context creation raises import error.
  • You can check whether these functions are available or not by running display_analytic_functions().
    • If these functions are available for the corresponding Vantage version, then display_analytic_functions() displays the functions.
    • Otherwise, these functions are not displayed in display_analytic_functions() output.
