Azure Blob Store

The Azure Blob Store output allows you to write output features to files in an Azure Blob Store.

Example

After performing analysis in a big data analytic, a researcher wishes to write the output spatial or tabular features to files in an Azure Blob Store.

Usage notes

  • The Dataset parameter specifies the name of the folder that Velocity will write to the Azure Blob Store. This folder will contain one or more files, depending on the size of the output.
  • Your account key will be encrypted the first time you save your analytic and stored in an encrypted state.
  • When specifying the folder path, use forward slashes (/). /
  • This output is only available in big data analytics.
  • Any folder specified in the Folder Path parameter must exist and have content within it before data can be exported to this folder.
