Use the cdf data download command to download data from Cognite Data Fusion (CDF) to your local machine. This command provides multiple subcommands for downloading different types of data, including raw tables, assets, time series, events, files, hierarchies, instances, and charts. All subcommands have an interactive prompt if you do not specify any arguments, making it easy to select what you want to download.

​
Prerequisites

Before downloading data, ensure you have:
  • Installed and configured the Cognite Toolkit.
  • Authenticated with CDF using appropriate credentials.
  • Read permissions for the data you want to download.
  • Sufficient disk space for the downloaded files.
